Computer forensics has become an important technology in providing evidence in investigations of computer misuse, attacks against computer systems and more traditional crimes like money laundering and fraud where digital devices are involved. Investigators frequently perform preliminary analysis at the crime scene on suspects‟ devices to determine the existence of any inappropriate materials such as child pornography on them and conduct further analysis after the seizure of computers to glean leads or valuable evidence. Hence, it is crucial to design a tool which is portable and can perform efficient instant analysis. Many tools have been developed for this purpose, such as Computer Online Forensic Evidence Extractor (COFEE), but unfortunately, they become ineffective in cases where forensic data has been removed. In this thesis, we design a portable forensic tool which can be used to compliment COFEE for preliminary screening to analyze unallocated disk space by adopting a space efficient data structure of fingerprint hash tables for storing the massive forensic data from law enforcement databases in a flash drive and utilizing hash tree indexing for fast searching. We also apply group testing to identify the fragmentation point of the file and locate the starting cluster of each fragment based on statistics on the gap between the fragments. Furthermore, in order to retrieve evidence and clues from unallocated space by recovering deleted files, a file structure based carving algorithm for Windows registry hive files is presented based on their internal structure and unique patterns of storage. / UOIT

Syftet med denna uppsats har varit att undersöka på vilket sätt attacker utförda av al-Qaida kanhänföras till begreppet asymmetri och på vilket sätt man kan tolka den amerikanska administrationensrespons på dessa som uttryck för ett linjärt tänkande. Vidare vill jag undersöka vilka svårigheter somkan uppstå i relationen mellan en linjär omvärldsuppfattning och asymmetriska metoder. För attuppfylla syftet med uppsatsen kommer tre av al-Qaidas attacker att studeras. Dessa är: attacken mot deamerikanska ambassaderna i Afrika, 1998, attacken mot USS Cole, 2000 och attacken 11 september,2001. Rapporterna från den amerikanska administrationen efter respektive attack kommer att utgöragrunden i mitt empiriska material. Teorianknytningen grundar sig i Linda Beckermans teori om thenon-linear dynamics of war samt Steven Metz och Douglas Johnsons definitioner på asymmetri. En avuppsatsens slutsatser avseende USA och dess krig mot al-Qaida är att USA bör utveckla sinanpassningsförmåga, och för att göra detta måste deras omvärldsuppfattning och förståelsehorisontvidgas. Detta skulle sammantaget medföra en större beredskap för oväntade händelseutvecklingar samtmedföra en ökad möjlighet att ta rätta beslut, både på lång och kort sikt. / The aim of this essay has been to investigate in what way attacks made by alqaidaare assignable to what is called asymmetric warfare, and in what way youcan interpret the American administration´s response and actions to thoseattacks as a result of linear thinking. Furthermore I want to analyse whatdifficulties that may appear in the relationship between linear thinking andasymmetric methods. To support and fulfil this aim I shall investigate threeattacks committed by al-Qaida, these are: the bombing of the Americanembassies in Africa in 1998, the attack on USS Cole in 2000 and the attacks on11 September 2001, and the subsequent reports made from institutions in theAmerican administration. To interpret and fulfil the purpose of the essay I useLinda Beckerman´s theory about the non linear dynamics of war, and StevenMetz´s and Douglas Johnson´s definition and theory of asymmetric forms anddimensions. One conclusion is that the United States must improve their abilityto identify the world around them and consequently improve their adaptability.In order to do this they have to broaden their horizon of comprehension andthus be better prepared for unexpected developments of events which wouldimprove the possibility of taking the right action in both short and long termperspectives. / Avdelning: ALB - Slutet Mag 3 C-upps.Hylla: Upps.

Waste management is a global environmental issue which concerns about a very significant problem in today’s world. There is a considerable amount of disposal of waste without proper segregation which has lead to both economic and environment sufferings. It is still practiced in many cities. There is a tremendous amount of loss in terms of environmental degradation, health hazards and economic descend due to direct disposal of waste. It is better to segregate the waste at the initial stages where it is generated, rather than going for a later option which is inconvenient and expensive. There has to be appropriate planning for proper waste management by means of analysis of the waste situation of the area. This paper would deal with, how Geographical Information System can be used as a decision support tool for planning waste management. A model is designed for the case study area in an Indian city for the purpose of planning waste management. The suggestions for amendments in the system through GIS based model would reduce the waste management workload to some extent and exhibit remedies for some of the SWM problems in the case study area. The waste management issues are considered to solve some of the present situation problems like proper allocation and relocation of waste bins, check for unsuitability and proximity convenience due to waste bin to the users, proposal of recyclable waste bins for the required areas and future suggestions. The model will be implemented on the Aurangabad city’s case study area data for the analysis and the results will suggest some modification in the existing system which is expected to reduce the waste management workload to a certain extent.

Abstract ¡§The economic miracle of Taiwan¡¨ is the result of heavy interference of the State into economic development. After democratization, the State is not as convenient as it was with the authoritative period, as far as economic sector is concerned. The case for Bin-nan industrial exploit should be able to increase national income for 1%, but stalled for 11 years, it stays at the origin. It means that the State has lost the autonomy in forming and setting up policies that are closely related to the welfare of the public. Utilizing the Model of The theory of Claus Offe¡¦s system analysis for exploring the changes in autonomy of state after democratization, aided with case for Bin-nan industrial exploit, we discussed the economic, legitimate, and political sub-system and made throughout interpretation. It is clear that in the highly controversial case for Bin-nan industrial exploit, the State slowed down the pace of development approval in exchange of support of the administration of the public and left the capitalists to communicate and negotiate with the local and social groups. The State expressed its support of the project orally on the one hand and assist in administration operations to avoid capital flee on the other hand, which avoid the non-support of current administration from the public due to full support of capitalist, which may lead to the legitimacy crisis of the administration. During the economic development process after democratization of Taiwan, the State is still holding the dominating position in the implementation of mercantilism and is still playing the initiative role in economic development and continues in promoting capital accumulation and in pushing industried technology. The will in developing economy has indicated that the State has its preoccupies position, so the State inevitably has dual consideration in the selection of autonomy policy, which is expecting continuous capital accumulation and securing the consent from the people for its legitimate ruling base.

Whether you are in industrial manufacturing striving to optimize your supply chain, international or domestic carrier committed to lower your operational costs, retailer dedicated to run your distribution network more efficiently, or anywhere else where the words "cargo", "freight", "shipment" are in your business language, automated load planning and optimization will significantly improve your business process. While the concept of computerized simulation of 3D load building is not new, with some companies offering software solutions for "virtual" loading, no one has a single product that is capable to handle complex variety of business rules and constraints of the modern transportation industry. We are analyzing the problems related with 3D box loading and then to analyze existing 3D load building systems. After accumulating all analyzes data we are having enough experience to create our own algorithm. And we did it! We create 3D box loading algorithm witch is fast and accurate and 3D box loading system which is using this new algorithm. To ensure that we succeeded we compare this new system with existing 3D box loading software to make sure that it’s really useful for solving logistic problems. After testing we are sure that we made a big job and we have created system, which can compete with the logistic IT leaders made solutions.

La capacité à détecter des objets dans une scène et à estimer leur pose constitue un préalable essentiel à l'automatisation d'un grand nombre de tâches, qu'il s'agisse d'analyser automatiquement une situation, de proposer une expérience de réalité augmentée, ou encore de permettre à un robot d'interagir avec son environnement.Dans cette thèse, nous nous intéressons à cette problématique à travers le scénario du dévracage industriel, dans lequel il convient de détecter des instances d'un objet rigide au sein d'un vrac et d'estimer leur pose -- c'est-à-dire leur position et orientation -- à des fins de manipulation robotisée.Nous développons pour ce faire une méthode basée sur l'exploitation d'une image de profondeur, procédant par agrégation d'hypothèses générées par un ensemble d'estimateurs locaux au moyen d'une forêt de décision.La pose d'un objet rigide est usuellement modélisée sous forme d'une transformation rigide 6D dans la littérature. Cette représentation se révèle cependant inadéquate lorsqu'il s'agit de traiter des objets présentant des symétries, pourtant nombreux parmi les objets manufacturés.Afin de contourner ces difficultés, nous introduisons une formulation de la notion de pose compatible avec tout objet rigide physiquement admissible, et munissons l'espace des poses d'une distance quantifiant la longueur du plus petit déplacement entre deux poses. Ces notions fournissent un cadre théorique rigoureux à partir duquel nous développons des outils permettant de manipuler efficacement le concept de pose, et constituent le socle de notre approche du problème du dévracage.Les standards d'évaluation utilisés dans l'état de l'art souffrant de certaines limitations et n'étant que partiellement adaptés à notre contexte applicatif, nous proposons une méthodologie d'évaluation adaptée à des scènes présentant un nombre variable d'instances d'objet arbitraire, potentiellement occultées. Nous mettons celle-ci en œuvre sur des données synthétiques et réelles, et montrons la viabilité de la méthode proposée, compatible avec les problématiques de temps de cycle, de performance et de simplicité de mise en œuvre du dévracage industriel. / Visual object detection and estimation of their poses -- i.e. position and orientation for a rigid object -- is of utmost interest for automatic scene understanding.In this thesis, we address this topic through the bin-picking scenario, in which instances of a rigid object have to be automatically detected and localized in bulk, so as to be manipulated by a robot for various industrial tasks such as machine feeding, assembling, packing, etc.To this aim, we propose a novel method for object detection and pose estimation given an input depth image, based on the aggregation of local predictions through an Hough forest technique, that is suitable with industrial constraints of performance and ease of use.Overcoming limitations of existing approaches that assume objects not to have any proper symmetries, we develop a theoretical and practical framework enabling us to consider any physical rigid object, thanks to a novel definition of the notion of pose and an associated distance.This framework provides tools to deal with poses efficiently for operations such as pose averaging or neighborhood queries, and is based on rigorous mathematical developments.Evaluation benchmarks used in the literature are not very representative of our application scenario and suffer from some intrinsic limitations, therefore we formalize a methodology suited for scenes in which many object instances, partially occluded, in arbitrary poses may be considered. We apply this methodology on real and synthetic data, and demonstrate the soundness of our approach compared to the state of the art.

As características trativas de um pneu dependem do tipo e condições do solo, tipo e geometria do pneu, formato das suas garras, carga no eixo e pressão de inflação do pneu. Este trabalho teve como objetivo quantificar e avaliar o contato pneu/solo com ênfase nos métodos para a obtenção da área de contato. A abordagem, visando uma solução analítica para o caso, seria de difícil execução e imprecisa, não fosse o uso da técnica de Elementos Finitos que tem demonstrado versatilidade, flexibilidade e excelentes resultados em casos semelhantes. A área de contato do pneu com o solo é a responsável, em grande parte, pelo desempenho do trator, afetando também características como, a patinagem de pneus e a tração. A abordagem do problema, em primeira instância, considerou um delineamento experimental com parcelas sub-divididas constituído de 48 tratamentos, assim distribuídos: a) Três tipos de pneu: Diagonal, Radial e BPAF (baixa pressão de inflação e alta flutuação). b) Dois níveis de pressões de inflação do pneu: Alta: 165,50 kPa (17 psi, pneus montados no eixo traseiro do trator), Baixa/correta para pneus montados no eixo traseiro do trator: 68,95 kPa (7 psi) ou para cada tipo de pneu respectivamente. c) Quatro magnitudes de carga vertical aplicada no pneu: 0,5 kN, 1,0 kN, 1,5 kN e 2,0 kN. d) Dois tipos de solo: amostra de solo agrícola arenoso ( s= 1,4g/cm3) e amostra de solo agrícola argiloso ( s= 1,2g/cm3). Para realização do experimento com os dois tipos e condições de solo, foi utilizado um equipamento para o ensaio estático de pneus individuais, denominado tanque de solo com dispositivo hidráulico de aplicação de carga... . / The tractive efficiency of tractors equipped with inflated tires varies from nearly 90%, whem working on concrete, to less than 50% when working on loose soil or sand. The tractive characteristics of a tire depend on soil conditions, tire geometry and lugs, axle load and tire pressure. This wok aimed to estimate the contact tire/soil with emphasis on methods of determination of contact area. The approach using an analytical solution for this case wold of hard execution and inaccurate, but the use of the finite element solutions has been shown versatile, flexible and with exelents results in similar cases. The contact area of tire with the soil is the major responsible by the performance, affected also characteristics like sliding and traction. The problem was considered like an experimental design with 48 treatments being: a) Tree kinds of the tires, bias, radial and B.P.A.F. (low inflation pression and high flutuation). b) Two levels of inflation pressure of the tire, high: 165,50 kPa for each kind of tire, respectively. c) Two types of soil: sample of agricultural sandy soil ( s= 1,4g/cm3) and sample of agricultural clay soil ( s= 1,2g/cm3). To realize the experiment with two soil types and conditions were used an equipment for static test of individual tires named soil bin with hydraulic device to apply the loads. For each test the tire/soil contact area was determinate using a method of digital picture area integration. The data were used to elaborate mathematical models that expressed the relation ships among loads and strains using the Finite Element Method. The tests proved that relationship to determine the contact areas for bias tires gained the worst results once the B.P.A.F. tires showed the bests one. The Radial tires showed always intermediates results compared with the other two types. The pressure cells installed into the soil bin always showed...

It’s considered the existence of multiple containers ofthe equal dimensionsthat promote the full loading of the availablecargoinindustrial transportation context. Thisload is composed ofstrongly heterogeneous assortment to the boxes, and allows rotation in any of the six possibilities, making the problem even more complex, and therefore less studied in the literature. A bibliographic review is also presented, containing an overview of the classifications of the problem and, in particular, an deepened study on genetic algorithms. The implementation of AGE-E was performed, and the computational results were compared with the best solutions already determined by the bibliography, demonstrating the potentialofAGE-E for future studies.
