ABSTRACT Almost people hurt or die because of heavy smoke when the building fires. Smoke Management is to keep the smoke in the limited zone or to change its direction and to keep the ways which the people escape bright. It is convenient for fireman to save them and to keep their life and to reduce the money loss. In the developed country of the world, smoke management design is one of the most important factors to affect egress system of the building. Effective smoke management design is to avoid the smoke diffusing or descending and to make the people have enough time to escape. The combination of smoke management and egress system using performance-based fire safety design should be developed safely and economically. In Taiwan,we haven¡¦t the proper law of smoke management and egress system about the atria of the large space. So we must progress the computer simulation about smoke management and egress system and then use full-scale experiment to perform. The major terms of the content are: 1.the optimal distribution zone analysis of smoke management of the building. 2.to design and to analyze smoke management of the atria. 3.the combination of design analysis of smoke management and egress system. 4.full-scale experimental investigation. We hope that the performance-based fire safety design method about smoke management and egress system of the large shopping mall could be the excellent model and enchance the safety of the building in Taiwan.

In order to promote the reputation, appearance, social position and job achievements of the police, the superior moral is the key factor. It affects the performance of authority and the quality of governance of our government directly. The moral crisis is more or less hidden in the government apparatus. However, the law executor like the police involves a moral case will always be the headlines, it proves ¡§Rotten Apple Theory¡¨, even there is 99¢H law-abiding police officers. The image of the police in the people¡¦s mind should be the incarnation of equity and justice. Nevertheless, the authority is endowed by the police is the best sharp weapon of law-disobeying and discipline-violating. The citizen has the right of the examination and being public employment. According to ¡§Civil Service Employment Act¡¨, the citizen can be a formal police officer by passing the national examination. However, according to ¡§The Statute For Personnel Affairs Involving Police Staff¡¨, counterbalancing a police officer¡¦s prize and punishment are two serious mistakes will be dismissed from office, it seriously takes effects on the police¡¦s right. The superintendents who are responsible for the investigation on the police moral cases should handle matters carefully, administrate legally, obey the rule of procedural justice. To examine the practice and enactment of the investigation on the police moral cases by the administrative legal system is necessary in this studying. The legal system of the investigation on the police moral cases is examined herein by the basic methods of administrative law, namely, the five major frameworks, including administrative principles, administrative organization, limitation of administrative power, administrative relief, and administrative supervision from every respect and viewpoint. Meanwhile, bibliography exploration, historical narration, comparative research, and case analysis are adopted as the principal research approaches to explore whether there¡¦s any improvement required regarding the legal system of the investigation on the police moral cases on the basis of five major frameworks of administrative law. Additionally, practical implementation and suggestions for regulations and actions concerning future investigation on the police moral cases are hereby provided to achieve the goal of protecting procedural justice and the police¡¦s right as well. With the exploration by means of five major frameworks of administrative law, the legal system of the investigation on the police moral cases yet obeys the three administrative principles according to laws and the seven principles of procedural justice and has formed the prototype as that of countries ruled by law. However, problems such as inappropriate system design of special duty and administrative plan , incomplete decrees and laws, uncertain legal concepts, unclear meanings still remained in the existing and getting rid of the traditional concept of ¡§special right relation¡¨. As a whole, restriction exceeds protection. The suspect against ¡§Criminal Code¡¨ is still possessed with legal human rights, the police against administrative law shouldn¡¦t be possessed with human rights procedurally and substantively. Indeed, ¡§ moral is the lifeblood of the police¡¨, since moral is so important, the governor of the police authorities shall view that to be a topic of demanding immediate attention and examine the problems dwelling in the legal system of the investigation on the police moral cases on the basis of five major frameworks of administrative law as soon as possible and further to review and perform modification to be convinced of all the police and promote the police¡¦s appearance and public reliance.

Time has changed. The police can no longer take it for granted that they can conduct ¡§household investigation¡¨ simply on the basis of the 9th article of Police Law. After lifting of the martial law in July 15, 1987, Taiwan government observed its constitution and instituted a new system, Police House Visitation Practice, by the Interior Ministry to continue the practice of monitoring its citizenry. However, the 5th and 6th articles of this law which stipulated the citizens¡¦ obligations and penalties were apparently in violation of a higher law, Administrative Procedure Law. In particular they are against the 150th and the 158th articles of Administrative Procedure Law which maintains that acts or regulations should have their bases on law and should not against the spirit of this law (150th article) and these acts and regulation should be nullified if they have no basis of law and they infringe the rights and freedom of movement of its citizenry (158th article). Based on these principles, the 9th article of Police Act was therefore abolished by the Interior Ministry in October 31, 2000. In July of 2007, the 1st item of the 11th article of Police Operation Practice was amended and specifies that: ¡§The Interior Ministry should stipulate the policies for police officers in their beats to visit households, to provide service, to investigate and to maintain the social order.¡¨ The 60-year practice of police ¡§household investigation¡¨ becomes a history. Household investigation is no long the main theme of police activities, instead other major functions such as crime prevention, service and social security survey are the main focuses of police operations. This study examines and evaluates the soundness of police beat investigation from the perspectives of the basic theories of administrative law including five (5) major frameworks of administration: principles, organizations, authorities, remedies and supervision. This study also seeks to identify the potential problems and discuss the feasible remedies for any deficiency of this act. And finally policymakers can make good use of the findings and recommendations of this study to enact sound police polices to promote and protect the well-being of their constituents.

<p>The structural quality of material (concentration and nature of defects) and optical properties (intensity and spectral emission range) of semiconductor materials are usually closely correlated. The idea of this work was to carry out a basic characterization of the structural (by X-ray diffraction technique and scanning electron microscopy) and optical (by micro photoluminescence measurements) properties of nanocrystalline ZnO samples and find a correlation. A number of ZnO samples prepared by atmospheric pressure metalorganic chemical vapor deposition at different regimes and on different substrates were investigated. According to the aim of the work the most important results can be summarized as following. The analysis of ZnO nanocrystalline structures deposited on Si (100) substrates have displayed a dependence of structural quality, morphology and microstructure as well as the optical spectral purity on the deposition temperature. The deposition at 500 ºС resulted in the massive of 1D ZnO nanopillars that demonstrated the best optical properties: a mono-emission in the ultraviolet spectral range was observed. Moreover, the results of microstructure investigation give a suggestion to the explanation of the ZnO nanopillars growth. The results obtained from ZnO on sapphire substrates revealed a moderate influence of the oxygen content during deposition on the structural quality of zinc oxide. However, a strong correlation between the oxygen content and deep-level emission intensity from ZnO nanostructures has been observed, which confirms the determinative role of oxygen for the defect emission from ZnO. It was shown that during the deposition of ZnO on specially prepared homoepitaxial template the substrate surface has not the major effect on the morphology of depositing ZnO structures. SiC was revealed to be the most appropriate substrate for hetero-deposition of textured ZnO nanostructures: the growth results in the massive of epitaxially related ZnO hexagons on the SiC (0001) plane. A number of factors - p-type conductivity of the substrate used, regular and uniform epitaxial growth of ZnO nanostructure, their excellent mono-spectral emission in short wavelength range of spectra, provides a strong background for further investigation of the electroluminescence properties of the obtained heterostructures and are of great importance for the progress of optoelectronics towards low-scaled elements.</p>

The United States entered World War I in April, 1917, amid a German spy scare. There were persistent allegations that Blacks were opposed to the war, in spite of their declarations to the contrary. "ProGermanism among the negroes" was investigated by the Justice Department's Bureau of Investigation and the Military Intelligence Branch (MIB) of the War Department's General Staff. Efforts were made to discover disloyal motives behind orgnnisatione such as the NAACP and the National Equal Rights League; in the contents of publications such as the Crisis, the Messenger and the Chicago Defender; and in the activities of Black spokesmen such as W E B Du Bois, and Monroe Trotter, Kelly Miller, A Philip Randolph, Chandler Owen, and Hubert Harrison. No firm evidence was found to support claims that Blacks were disloyal, but investigation of what MIB called "Negro Subversion" became a regular part of domestic intelligence gathering during the war. Reports filed about Blacks were often inaccurate and the resulting misinformation was self-perpetuating. Black draft evasion, which was common, but not always deliberate, and rumours about harsh conditions and high casualty rates endured by Black troops were the subject of numerous reports by the Bureau and MIB, enhancing the misleading impression that there was a well-co-ordinated enemy plan to foment racial discord. The behaviour of Black soldiers was monitored by MIB. Particular attention was given to camp race riots and to the political views of Black YMCA staff. Joel E Spingarn, the white chairman of the NAACP, served as a military intelligence officer for 21 months in 1918. He attempted to persuade the General Staff to sponsor federal anti-lynching legislation and began to set up a subsection within MIB to identify those instances of racial discrimination which most damaged Black morale. Spingarn was ousted from MIB after his proposal that Du Bois be brought into military intelligence aroused bitter Black criticism. Had he remained in Washington, the subsequent attitude of federal government toward intervention in the field of race relations might have been different. In the final months of the war, MIB was re-organised and re-named the Military Intelligence Division (MID). Efforts of Blacks to travel to Paris to raise the question of race during the peace conference were in most cases foiled by the State Department's refusal on spurious grounds to grant them passports. At the same time, the return from France of Black troops with greater political and racial awareness than before the war was anticipated with some concern by military intelligence officers. The menace of the German agent was swiftly replaced in the American mind by the spectre of Bolshevism. In 1919 radical Black protest and organisation began to be attributed to the influence of the new alien threat. Randolph, Owen and Marcus Garvey were among those leaders watched by the federal investigative agencies in attempts to discover evidence of Bolshevik influence among Blacks. Race riots in Washington, UDC, and Chicago in July served to convince many officials, notably J Edgar Hoover, head of the Bureau's Radical Division, that some link must exist between Black protest, racial violence and Bolshevism. MID work on "Negro Subversion" was being scaled down, but the Radical Division maintained its interest in this area in the light of further riots. The climax of the Red Scare was accompanied by statements from the Justice Department that Blacks were part of the radical tide which threatened to sweep America. Blacks did not, in fact, adopt radical politics in significant numbers. However, in the minds of those who ran the investigative agencies of federal government, Blacks were now firmly established as a potentially disloyal and revolutionary element in American society - ever susceptible to, and the likely target of, the advances of subversive propagandists.

This dissertation develops statistical and data mining based methods for insurance fraud detection. Insurance fraud is very costly and has become a world concern in recent years. Great efforts have been made to develop models to identify potentially fraudulent claims for special investigations. In a broader context, insurance fraud detection is a classification task. Both supervised learning methods (where a dependent variable is available for training the model) and unsupervised learning methods (where no prior information of dependent variable is available for use) can be potentially employed to solve this problem. First, an unsupervised method is developed to improve detection effectiveness. Unsupervised methods are especially pertinent to insurance fraud detection since the nature of insurance claims (i.e., fraud or not) is very costly to obtain, if it can be identified at all. In addition, available unsupervised methods are limited and some of them are computationally intensive and the comprehension of the results may be ambiguous. An empirical demonstration of the proposed method is conducted on a widely used large dataset where labels are known for the dependent variable. The proposed unsupervised method is also empirically evaluated against prevalent supervised methods as a form of external validation. This method can be used in other applications as well. Second, another set of learning methods is then developed based on the proposed unsupervised method to further improve performance. These methods are developed in the context of a special class of data mining methods, active learning. The performance of these methods is also empirically evaluated using insurance fraud datasets. Finally, a method is proposed to estimate the fraud rate (i.e., the percentage of fraudulent claims in the entire claims set). Since the true nature of insurance claims (and any level of fraud) is unknown in most cases, there has not been any consensus on the estimated fraud rate. The proposed estimation method is designed based on the proposed unsupervised method. Implemented using insurance fraud datasets with the known nature of claims (i.e., fraud or not), this estimation method yields accurate estimates which are superior to those generated by a benchmark naïve estimation method. / text

Fire models are routinely used to evaluate life safety aspects of building design projects and are being used more often in fire and arson investigations as well as reconstructions of firefighter line-of-duty deaths and injuries. A fire within a compartment effectively leaves behind a record of fire activity and history (i.e., fire signatures). Fire and arson investigators can utilize these fire signatures in the determination of cause and origin during fire reconstruction exercises. Researchers conducting fire experiments can utilize this record of fire activity to better understand the underlying physics. In all of these applications, the fire heat release rate (HRR), location of a fire, and smoke production are important parameters that govern the evolution of thermal conditions within a fire compartment. These input parameters can be a large source of uncertainty in fire models, especially in scenarios in which experimental data or detailed information on fire behavior are not available. To better understand fire behavior indicators related to soot, the deposition of soot onto surfaces was considered. Improvements to a soot deposition submodel were implemented in a computational fluid dynamics (CFD) fire model. To better understand fire behavior indicators related to fire size, an inverse HRR methodology was developed that calculates a transient HRR in a compartment based on measured temperatures resulting from a fire source. To address issues related to the uncertainty of input parameters, an inversion framework was developed that has applications towards fire scene reconstructions. Rather than using point estimates of input parameters, a statistical inversion framework based on the Bayesian inference approach was used to determine probability distributions of input parameters. These probability distributions contain uncertainty information about the input parameters and can be propagated through fire models to obtain uncertainty information about predicted quantities of interest. The Bayesian inference approach was applied to various fire problems and coupled with zone and CFD fire models to extend the physical capability and accuracy of the inversion framework. Example applications include the estimation of both steady-state and transient fire sizes in a compartment, material properties related to pyrolysis, and the location of a fire in a compartment. / text

In computer forensics, digital evidence related to time is both important and complex. The rules of changes in time associated with digital evidence, such as files or folders, can be used to analyze certain user behaviors like data access, modification or transfer. However, the format and the rules in time information for user actions are quite different for different file systems, even for different versions of operating systems with the same file system. Some research on temporal analysis has already been done on NTFS and FAT file systems, while there are few resources that describe temporal analysis on the Hierarchical File System Plus (HFS+), the default file system in Apple computer. Moreover, removable devices like USB disks are used frequently; transferring files and folders between different devices with different file systems and operating systems happens more and more frequently, so the changes of times across different file systems are also crucial in digital forensics and investigations. In this research, the changes in time attributes of files and folders resulting from user actions on the HFS+ file system and across file systems are analyzed, and the rules of time are generated by inductive reasoning to help reconstruct crime scenes in the digital forensic investigation. Since inductive reasoning is not definitely true compared with deductive reasoning, experiments are performed to validate the rules. The usage of the rules is demonstrated by analyzing a case in details. The methods proposed here are efficient, practical and easy to put into practice in real scenarios. / published_or_final_version / Computer Science / Master / Master of Philosophy

In an infectious animal disease outbreak, effective management of the event requires timely and accurate information collection, processing, storage and distribution. This thesis focuses on the tools to assist information collection and management. The first study describes the comparison of questionnaire methodology for the information collection in the initial epidemiologic investigation of a Canadian federally reportable disease. The second study defines attributes of an animal disease outbreak information management system (IMS). The studies were performed within a one-year period (July 2013-July 2014). The first study performed two comparisons to determine differences in the information quality (completeness and accuracy) between differing questionnaire methodology and modes of completion (hard copy and electronic). The study was conducted with 24 Canadian Food Inspection Agency (CFIA) inspectors and veterinarians using a fictitious Canadian reportable disease scenario. The first comparison used a hard copy of a Canadian Food Inspection Agency (CFIA) questionnaire designed to be applicable (or generic) for all highly infectious reportable disease investigations with a supplementary disease specific section compared to an electronic disease specific reportable disease questionnaire. There was no significant difference in the information quality (N = 22; P = 0.09). The mean difference in completeness and accuracy scores was 3.5% (95% CI -0.6, 7.6). The second comparison focused on the hard copy disease questionnaire and assessed differences in information quality between using only the generic sections of the questionnaire compared to the supplementation of a disease specific section. A difference in information quality was determined (N = 24; P < 0.0001). The mean completeness and accuracy score for the generic only sections was 50.2% (95% CI 43.6, 57.2) compared to 80.2% (95% CI 76.2, 84.5) with the inclusion of the disease-specific section. The greatest difference in information quality occurred in the tracing specific information categories (P < 0.0001) with a mean difference of completeness and accuracy scores of 67.7% (95% CI 52.0, 83.4) for the trace-in (exposure history) category and 38.3% (95% CI 28.3, 48.3) for the trace-out (potential spread of disease) category. The absence of disease-specific questions were determined to be the primary factor in the difference in information quality. The second study determined a comprehensive list of user-defined attributes of an animal disease outbreak IMS and further identified the most important (key) attributes. A list of 34 attributes and associated definitions were determined through a series of focus group sessions and two surveys of Canadian animal health stakeholders. The animal health stakeholders included federal and provincial governments, veterinary academia and animal production industry representatives. The key attributes of an animal disease outbreak IMS identified were: ‘user friendly’, ‘effectiveness’, ‘accessibility’, ‘data accuracy’, ‘reliability’ and ‘timeliness’. ‘User friendly’ received the highest frequency of ranking as the most important attribute, followed by ‘effectiveness’. Information management was identified as the main purpose of an animal disease outbreak IMS with a median rating of 10 (rating scale of 0-10 with 10 = strongly agree). The occurrence of a federally reportable disease or a large-scale animal disease outbreak can have a great impact on the animal agriculture sector, regulatory government agencies and the economy. Information collection and management are essential to assist with the epidemiologic investigation and disease control measures. The study provided a novel opportunity to study information management for an animal disease outbreak from a Canadian perspective. The knowledge obtained will add value to the future development of tools and systems designed for information collection and management involving an animal disease outbreak.
