    PROCESS FOR BREAKING DOWN THE LTE SIGNAL TO EXTRACT KEY INFORMATION

    The increasingly important role of Long Term Evolution (LTE) has increased security concerns among the service providers and end users and made security of the network even more indispensable. The main thrust of this thesis is to investigate if the LTE signal can be broken down in a methodical way to obtain information that would otherwise be private; e.g., the Global Positioning System (GPS) location of the user equipment/base station or identity (ID) of the user. The study made use of signal simulators and software to analyze the LTE signal to develop a method to remove noise, breakdown the LTE signal and extract desired information. From the simulation results, it was possible to extract key information in the downlink like the Downlink Control Information (DCI), Cell-Radio Network Temporary Identifier (C-RNTI) and physical Cell Identity (Cell-ID). This information can be modified to cause service disruptions in the network within a reasonable amount of time and with modest computing resources.Defence Science and Technology Agency, SingaporeApproved for public release; distribution is unlimited

    The effect of a psychological climate for creativity on job satisfaction and work performance

    The organisational climate for creativity has been widely acknowledged to influence various work outcomes such as employee innovation and productivity. Researches carried out on the creative climate in Malaysia have up till now, confirmed the notion. However, as far as the Malaysian context is concerned, the effect of a creative work environment on employee job satisfaction and work performance level has yet to be explored. As such, this study aims to investigate the effects of a psychological climate for creativity on job satisfaction and work performance. Additionally, this study seeks to establish the role of job satisfaction as a mediator on the relationship between organisational climate and work performance. The results from a sample of 118 electrical engineers working only within the area of the Klang Valley suggest that all variable relationships were positively and significantly correlated: Job satisfaction - Work performance, Psychological climate for creativity - Job satisfaction and Psychological climate for creativity - Work performance. Moreover, job satisfaction was found to mediate between the psychological climate for creativity and work performance when an analysis was carried out on three separate regressions

    The influence of demographic variables on lecturers’ protean careers orientation

    The present study examined the influence of age, level of education and gender on two dimensions of the protean career orientation: values-driven attitude and self-directed behaviour. The results, based on 582 university lecturers, showed that age was a significant predictor for the values-driven attitude while educational level was a significant predictor for the self-directed attitude. Gender was significant for both values-driven attitude and self-directed attitude. For both these dimensions, female lecturers scored higher than male lecturers, indicating that women were more intent on using their own values (versus organisational values) to guide their careers (values-driven) and possessed a self-directed attitude towards career management. The results of this study provided a further understanding of the factors that influence protean careerists. Furthermore, both research and managerial implications associated with values-driven attitude and self-directed attitude were discussed

    Viable short-term directed energy weapon naval solutions: a systems analysis of current prototypes

    With conventional weapons nearing their peak capability, the need to identify alternative war fighting solutions suggests a look at Directed Energy Weapons (DEWs). The goal is to change the means by which warfare is conducted to improve operational efficiencies and overall effectiveness. The Naval Postgraduate School Systems Engineering and Analysis (SEA-19B) Capstone project team examined how existing directed energy technologies can provide performance across multiple warfare area domains and mission subsets for the U.S. Navy. The aim was to identify and characterize the capability gaps with conventional weapons systems, produce a coherent vision of naval missions that incorporate DEWs, and generate a roadmap for a DEW fleet. By conducting a thorough Analysis of Alternatives based on system performance, integration, schedule, and cost, the project team identified that the Tactical Laser System (with a laser beam power of 10 kW) provided the best overall capability to defend surface combatants, although none of the analyzed DEWs have the capability to replace a current conventional weapon. The Active Denial System (microwave) provided a niche capability in the Anti-Terrorism/Force Protection mission set.http://archive.org/details/viableshorttermd1094534734Approved for public release; distribution is unlimited
