This thesis deals with criminalistic recontruction which is understood within criminal law as evidence, whereas criminology considers it as a criminalistic - tactical method. At the beginnig, this thesis follows up on the concept of recontruction, its main importance, its historical point of view and its conception within the other criminalistic methods. A very important part of the thesis is in the second chapter, where the types of criminalistic reconstruction are described. It is explained that the reconstruction of the crime as a specific method of criminalistic practice falls into the type of reconstruction of criminalistic significant negotiations and events. The main part of the thesis contains a detailed description of the reconstruction itself, especially its preparation, stages, procedural principles, tactical principles, methodological procedures, protocol, evaluation and documentation. Also, the case law of our courts when dealing with this issue, which often has a great impact on the possible development of this act is not forgotten. Particularly the most important findings of the Constitutional Court and decisions as well as resolutions of the High court are included. Furthermore, the comparative method is used and the legislation of the reconstruction in our Criminal Code Procedure is...

Firefighting is a strenuous occupation that requires high-intensity work, resulting in prolonged periods of stress and physical exertion. The physical demand of performing firefighting tasks is augmented by the weight of personal protective equipment (PPE) worn (i.e., load carriage: LC) and the use of a self-contained breathing apparatus (SCBA). These factors have been shown to increase metabolic demand at submaximal workloads and decrease maximal aerobic capacity in laboratory settings. However, there is limited research evaluating the effects of these factors on occupational performance. Therefore, the primary purpose of this study was to quantify the detrimental effect of LC only and LC+SCBA on firefighter occupational performance. In addition, it is important to identify fitness characteristics and physiological outcomes that are correlated to the decrement in performance produced by the PPE. This information will guide practitioners in selecting appropriate training strategies to effectively prepare firefighters to perform occupational tasks in gear. Thus, a secondary aim was to evaluate the relationships between fitness and pulmonary outcomes versus the decrement in occupational performance produced by the PPE. Twenty-one male firefighter recruits (Age: 28.6 ± 4.3 yr; Height: 178.6 ± 7.2 cm; Mass: 94.1 ± 15.4; Body Fat: 17.8 ± 8.4%) participated in this study. Occupational physical ability was assessed by time to complete a simulated fire ground test (SFGT). The SFGT was composed of the following tasks: stair climb, charged hose drag, equipment carry, ladder raise, forcible entry, search, and victim rescue. The recruits participated in six testing sessions. First, two SFGT familiarization trials were performed on separate days. During the next three testing sessions, the firefighter recruits performed the following SFGT conditions in a randomized order: control condition (PT clothes), LC only condition, and PPE+SCBA (SCBA) condition. Baseline and post-SFGT pulmonary and physiological data were collected. To describe within group differences between SFGT conditions, relative difference scores were calculated as follows: % difference = (([experimental trial outcome – PT trial outcome] / PT trial outcome) x 100). Statistical differences between the SFGT conditions were assessed with repeated measures ANOVA. To evaluate the relationship between fitness outcomes versus the decrement in SFGT performance, fitness testing data were obtained from the recruit academy and included: 1.5 mile run time, maximal push-ups, maximal sit-ups, maximal pull-ups, and prone plank time. In addition, the recruits completed a battery of fitness tests in their sixth testing session. The absolute difference in time to complete the SFGT between conditions was calculated as: experimental SFGT time - PT time. Bivariate correlations were used to assess the relationship between the absolute difference in SFGT time versus fitness outcomes. The LC+SCBA trial took 44.5 ± 15.5% longer (345.9 ± 43.7 s; p < .001) and the LC only trial took 38.3 ± 12.6% longer (331.2 ± 39.3 s; p < .001) to complete the SFGT than the PT trial (241.0 ± 33.3 s). The LC+SCBA trial took longer to complete the SFGT than the LC only trial (p = .046). Post-SFGT RPE was higher in the LC+SCBA trial (6.7 ± 1.7) and LC only trial (6.3 ± 1.5) compared to the PT trial (4.6 ± 1.8; p < .001). Absolute aerobic capacity, lower body power, anaerobic power and capacity, abdominal muscular endurance, and upper body strength were significantly correlated to the decrement in SFGT performance on some tasks caused by the PPE. In summary, PPE increases the intensity of performing fire ground tasks. To enhance occupational performance, it is imperative that firefighters optimize specific physical fitness attributes to reduce the relative stress produced by the PPE.

This thesis reports on a study that examined customer accounting (CA) in Australian companies. The broad aims of the thesis are to develop an understanding of the organisational role played by CA practice and the role accounting plays in providing information about a firm's customer base. Three empirical phases have been undertaken in the study. The first phase involved exploratory interviews with accountants and marketers from a number of Australian firms. The second phase comprised an in-depth case study that involved the development of a segmental customer profitability analysis in a major Australian telecommunications company. The third empirical phase involved the administration of a survey questionnaire to chief accountants and marketing managers from a number of large Australian companies. A number of significant findings are reported and include: (1) A level of CA practice has been observed that is reasonably in line with what was anticipated based on the minimal previous academic interest in this area. (2) There appears to be a potential for further CA development in Australian companies. (3) The interview findings identified 'short-term tactical decisions' and 'focus attention on maximising customer value' as the two most important organisational roles CA may play. (4) CA systems were found to provide important information for marketing resource allocation decisions, customer retention decisions, customer service management decisions and customer pricing decisions. (5) The main barriers to CA implementation identified during the segmental CPA case study and exploratory interviews concerned information technology and data acquisition problems. This finding was supported by the results of the survey questionnaire phase of the study where in addition to these two barriers, 'other competing organisational priorities' was rated highly as an impediment to CA system development. (6) Some support was found for the proposed relationships between CA and the contingent factors of company size, customisation, and organisational structure. (7) Limited support was found for the proposed positive association between CA systems and competition intensity and marketing orientation. (8) No support was found for the proposed relationships between perceived environmental uncertainty, organisational strategy, organisational performance and CA systems. (9) Customisation was the only contingent factor found to have a significant impact upon the potential of CA to aid management.

<p>Med anledning av att allt färre elever väljer språk som tillval på gymnasiet så är syftet med detta examensarbete att ta reda på vad som påverkar gymnasieelever att välja, respektive välja bort, språk som tillval. Det jag främst vill undersöka är ifall det finns skillnader i motivation, attityder och nöjdhet/missnöje med undervisningen mellan de som har valt språk och de som har valt bort språk som tillval. Vidare syftar undersökningen till att ta reda på vilka förbättringar både elever och lärare tycker vore nödvändiga. Metoden som användes var både kvalitativ och kvantitativ i form av intervjuer och två olika enkäter. Fyra elever och två lärare intervjuades och enkäterna besvarades av 34 elever med språk som tillval och av 40 elever med andra tillval. Resultatet visar inte på några specifika skillnader förutom motivation mellan grupperna, däremot fann jag flera möjliga orsaker till bortval; bland annat ointresse, taktikval och tråkig undervisning. De förbättringar som efterfrågades var till viss del organisatoriska, men till största delen handlade de om själva undervisningen. Det jag kom fram till är att undervisningen på högstadiet troligen påverkar bortvalen i hög grad och att det är förbättringar där, samt ett nytt skolsystem som premierar språk, som är de viktigaste faktorerna för att få fler elever att välja språk som tillval.</p> / <p>The purpose with this degree thesis is to find out why pupils choose, or do not choose, language as an optional subject. Mainly I want to see if there are any differences in motivation, attitudes and satisfaction/dissatisfaction with language teaching between the pupils who have chosen language and the pupils who have chosen another optional subject. Furthermore the investigation aims at finding out what improvements teachers and pupils find necessary. The method being used was both qualitative and quantitative in the form of interviews and two different questionnaires. Four pupils and two teachers were interviewed and the questionnaires were answered by 34 pupils with a language choice and 40 pupils with other choices. The result shows no specific differences except motivation between the two groups, however I found several possible reasons to why pupils tend to choose some other subject than language: lack of interest, tactical choices and an unsatisfying language teaching. The suggestions of improvements concerned to an extent organizational aspects, but mainly the actual teaching. The teaching in the upper level of compulsory school probably affects the fewer choices of language and we need to improve this teaching and introduce a new school system that rewards language choices to make more pupils choose language as an optional subject.</p>

We develop an extension to the tactical planning model (TPM) for a job shop by the third author. The TPM is a discrete-time model in which all transitions occur at the start of each time period. The time period must be defined appropriately in order for the model to be meaningful. Each period must be short enough so that a job is unlikely to travel through more than one station in one period. At the same time, the time period needs to be long enough to justify the assumptions of continuous workflow and Markovian job movements. We build an extension to the TPM that overcomes this restriction of period sizing by permitting production control over shorter time intervals. We achieve this by deriving a continuous-time linear control rule for a single station. We then determine the first two moments of the production level and queue length for the workstation. / Singapore-MIT Alliance (SMA)

Aircrafttrajectory optimization is traditionally used forminimizing fuel consumption or time when going from one flightstate to another. This thesis presents a possible approach toincorporate tactical constraints in aircraft trajectoryoptimization. The stealth technology of today focuses on making thetactics already in use more effective. Since tactics andstealth are closely interrelated, new and better results may beobtained if both aspects are considered simultaneously. Simplyreducing the radar cross section area in some directionswithout considering tactical aspects may result in little, ifany, improvement. Flight tests have been performed in cooperation withEricsson Microwave Systems and the Swedish Air Force FlightAcademy. The aircraft used was the subsonic jet trainer Saab105, designated SK60 by the Swedish Air Force. The results showa decrease of 40% in the time interval between the instant theaircraft was first detected until it could pass above the radarstation. This corresponds to a reduced radar cross section(RCS) in the direction from the aircraft to the radar of almost90%, if classical RCS reduction techniques would have beenapplied. If a modern aircraft with stealth properties would be used,the proposed methodology is believed to increase the possibleimprovements further. This is because the variation of themagnitude of RCS in different directions is greater for a shapeoptimized aircraft, which is the property exploited by thedeveloped method. The methods presented are indeed an approach utilizing theideas of the network centric warfare (NCW) concept. Themethodology presented depends on accurate information about theadversary, while also providing up-to-date information to theother users in the information network. The thesis focuses on aircraft but the methods are generaland may be adapted for missiles, shipsor land vehicles. Theproposed methods are also economically viable since they areuseful for existing platforms without costly modifications. Themethods presented are not limited to radar threats only. Thereasons for using radar in this thesis are the availablenon-classified data and that radar is known to pose a majorthreat against aircraft.

We consider a manufacturing system with stochastic demand and predictable production yield. The manufacturer has predetermined prices and limited production capacity in each period. The producer also has the option to save some inventory for future periods even if there is demand in the current period. The demand that is not met is lost or may be backordered for only one period. Our objective is to maximize the expected profit by choosing optimal production, save and backorder quantities in each period. We formulate this problem as a Markov Decision Process where the state of the system is represented by the net inventory and the efficiency parameter. We show that a modified (Y, S, B) policy is optimal in each period. At the end, we have some computational analysis to examine the effects of yield on the optimal decisions.

The aim of this study is to describe the conceptual design, performance analysis to validate the design and manufacturing steps of Middle East Technical University Tactical Unmanned Air Vehicle (METU TUAV). The system requirements are adopted from a market study and assumed as is. Utilizing competitor search and conceptual design methodology, the rough parameters of the aircraft are defined and a performance analysis is conducted to validate the requirements. After the design team is content that the design is meeting the requirements, material and production techniques are evaluated. The male and female molds of the aircraft are manufactured with glass fibre fabric and special mold resin. Using the female molds / with glass, carbon and aramid fibre materials and epoxy matrix / utilizing wet-layup and vacuum bagging techniques the METU TUAV is manufactured. Wing, tail and fuselage skins are manufactured first and the reinforcing structures are integrated and cured inside the skins. Then the skins are assembled and the separate components are obtained. The rear landing gear and tail booms are also manufactured from carbon fibre composites. The individual parts are assembled together in special alignment jigs and the METU TUAV is completed.
