Circumstances contributing to adolescents' vulnerability towards sexual abuse in a rural area / Marumo Nyabane Mamabolo

Mamabolo, Marumo Nyabane January 2014 (has links)
In rendering child care protection services to adolescents in the Marshite area as a social worker in the Department of Social Development, the researcher recognised that an increased number of adolescents are sexually abused also by persons known to them. The sexual abuses are not reported because adolescents and caregivers lacked adequate knowledge of what is sexual abuse and services provided by social workers available for them. This became evident from the intervention programme statistics which indicated that adolescents and caregivers were not aware of other sexually abusive behaviours than penetration. The aim of the research was to identify circumstances that contribute to adolescents’ vulnerability towards sexual abuse in a rural area in order to enable social workers to empower adolescents and caregivers on how to prevent sexual abuse. Also to develop and evaluate programmes and services rendered to sexually abused adolescents and their families. Purposive voluntary sampling was used to select adolescents participating in empowerment programmes of social workers in the Marshite area. The research reveals that children in the Marshite area lack sufficient knowledge on child sexual abuse. The circumstances within which the adolescents live in the Marshite area make the adolescents victims of sexual abuse. Looking at the services that social workers render to the sexually abused adolescents and their caregivers in te Marshite area, there is a need for skilled and knowledgeable forensic social workers who can develop empowerment programmes and render relevant services to sexually abused adolescents and their families in the Marshite community. / MSW (Forensic Practice), North-West University, Potchefstroom Campus, 2015

Performance of the IEEE 802.11b WLAN Standards for Fast-Moving Platforms

Kasch, William T., Burbank, Jack L., Andrusenko, Julia, Lauss, Mark H. 10 1900 (has links)
International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This paper addresses the physical and MAC layer performance of the IEEE 802.11b wireless local area networking (WLAN) standard in range-extended outdoor applications for high speed network platforms. Physical layer performance is quantified by bit error rate (BER) and packet error rate (PER) vs. range performance as well as acquisition and tracking performance considering Doppler effects caused by such high-speed platforms. This performance assessment is ascertained through the use of modeling and simulation and hardware-in-the-loop testing.

WIRELESS INFRA-RED SENSOR

Chaildin, Mark 10 1900 (has links)
ITC/USA 2006 Conference Proceedings / The Forty-Second Annual International Telemetering Conference and Technical Exhibition / October 23-26, 2006 / Town and Country Resort & Convention Center, San Diego, California / For several decades, the military has used the Multiple Integrated Laser Engagement System (MILES) with a series of iR sensors along a belt fastened to a vehicle for training and simulation. Now, an alternative to this legacy system, a solar rechargeable battery powered wireless IR sensor is replacing wired sensors. The use of short-range RF communications network, allows the MILES sensors strategic placement about a combat vehicle without the umbilical cabling normally required for power and signal coupling from the players processing unit. The RF network operates in the 340 to 380 MHz band, has channeling capability of over 1600 channels, and coexists with the vehicles on board high-powered radios without interference. The wireless sensor implements a custom designed IR sensing amplifier, designed for maximum sensitivity and minimal power dissipation, along with advanced semiconductor IC’s for signal processing and power conversion. Solar recharging enables the sensor to operate for extended time, on a single battery that should last for years without replacement. A proprietary software protocol, developed for communication integrity, is a critical part of the overall system and supports other sensor types and control elements with low data rates for a wireless Vehicle Area Network. The system, successfully installed on several military training platforms, proves to be a viable product for military training and simulation systems for the 21st century.

Analyse du couvert nival à l'aide de données radar polarimétriques multifréquences et des mesures terrain de la campagne CLPX (cold-land processes field experiments)

Trudel, Mélanie January 2006 (has links)
In this research, the characterization of snow cover is made from data collected in September, February and March of 2002 and 2003, during Cold-land Processes Field Experiments project of the NASA. These data include snow and forests characteristic measurements, meteorological conditions, digital elevation model (DEM) and polarimetric multifrequency SAR data (C, L and P bands) acquired from AIRSAR-POLSAR airborne sensor. These data will be used to analyze multifrequency polarimetric techniques to characterize snow cover over forested areas (open area, sparse coniferous forest, and dense coniferous forest). Different techniques have been developed to detect wet snow over different forested areas. The methodology of wet snow detection developed by Rott and Nagler (1995) is first analyzed. The best result is obtained in HH polarization (13% for the sparse coniferous forest site and 25% for the dense coniferous forest site). C-band data in circular polarizations improves these results, but the errors remain high (22% for the sparse coniferous forest site and 13% for the dense coniferous forest site). The use of [sigma][omicronn] ratio in dB [sigma][omicronn][subscript LHH] /[sigma][omicronn][subscript CHH], [sigma][omicronn][subscript LHV]/[sigma][omicronn] [subscript CHH], [sigma][omicronn][subscript LHV] /[sigma][omicronn][subscript CHV] and [sigma][omicronn][subscript LVV] /[sigma][omicronn][subscript CHH] allows to detect wet snow ([less-than or equal to] 13% errors) for both the open area and the dense coniferous forest sites. However, with this technique, higher errors ([greater-than or equal to] 16%) are obtained for the sparse coniferous forest site. The analysis of polarimetric signatures in the three bands shows that their shapes vary according to snow conditions (wet or dry) and forest densities. The pedestal height of polarimetric signatures in P band allows to apply a thresholding approach to discriminate between snow conditions (wet or dry). The error matrix generated from polarimetric signature techniques applied to snow pit measurements shows error higher than 6%. For the characterization of snow condition, target decomposition theorems show promising results. For the three bands, the Freeman-Durden and Cloude-Pottier decompositions allow to understand scattering mechanisms of snow-covered-forested areas. Also, a thresholding approach applied to volume scattering power of the Freeman-Durden decomposition in C band as well as to entropy parameter together with angle [alpha] value of Cloude-Pottier decomposition shows abilities to detect wet snow over forested areas. The technique using the volume scattered power shows detection errors higher than 16%. No classification error is obtained in the error matrix generated from entropy values over the snow pits. The analysis of backscattering coefficients as a function of forest density (open area, sparse coniferous forest and dense coniferous forest) shows variations in the signal as a function of frequency, polarization, density and forest structures as well as with ground conditions (snow-free, dry snow, wet snow). Three radar vegetation indexes (IVR, IVRD[subscript HH] and IVRD[subscript VV]) are analyzed. The IVR index in C and L bands, as well as the IVRD[subscript VV] index in L band are sensitive to forest density. The volume scattered power of the Freeman-Durden decomposition also allows to characterize forest density in C, L and P bands.In order to partially reduce the effect of forested area on the backscattering of a snow cover, image difference between the C-band backscattering coefficient (HH polarization) and the C-band volume scattered power in wet snow condition is performed. The error matrix generated over the snow pit shows that a threshold of 1.5 dB applied to the image difference leads to errors less than 6%. The obtained results clearly show the utility of multifrequency, multipolarisation and polarimetric SAR data for wet snow detection over different forested areas.

Wireless medium access control protocols for real-time industrial applications

Kutlu, Akif January 1997 (has links)
Wireless Communication is the only solution for data transfer between mobile terminals to access the sensors and actuators in industrial environment Control Area Network (CAN) is desirable solution for many industrial applications since it meets the requirements of real-time transfer of messages between systems. In situations where the use of a cable is not feasible it is important and necessary to design wireless medium access control protocols for CAN to provide real-time communications. This thesis deals with modelling, simulation and performance analysis of wireless medium access control protocols for CAN. The main issue in this concept is to determine prioritisation of the messages in the wireless environment. In order to accomplish this, a Wireless Medium Access Control protocol called WMAC is first proposed for distributed environment. The prioritisation in the WMAC protocol is achieved by performing an operation of timing the interframe gap. In this method, every message within the network is assigned a unique time period before the transmission of the message. These individual time periods distinguish messages from each other and provides message priority. Second access method called Remote Frame Medium Access Control (RFMAC) protocol is proposed for centralised wireless environment. Since the central node organises the message traffic the prioritisation is accomplished automatically by the central node. Both protocols are evaluated by using simulation techniques. The third access method called Comb is designed by using an additional overhead which consist of binary sequence. The prioritisation in this access method is managed by the overhead. Additionally, the interconnection of wireless nodes is investigated. The results of the simulations and performance analysis show that the proposed protocols operating in the centralised and distributed environments are capable of supporting the prioritisation of the messages required for real-time industrial applications in a wireless environment.

RT TELEMETRY NETWORK UPGRADE BASED ON ETHERNET

Taylor, Gene 11 1900 (has links)
International Telemetering Conference Proceedings / November 04-07, 1991 / Riviera Hotel and Convention Center, Las Vegas, Nevada / New techniques for using Ethernet in real time systems are applicable to the typical requirements of high performance Telemetry installations. Most TM installations around the world today are currently implemented using specialized, high speed, point-to-point data paths which have reached their limits in performance. By using Ethernet in real time as a “Data Highway” path, system performance is optimized, and the effective life of a Telemetry system can be significantly extended. Additionally, by integrating a Local Area Network into the system, further advantages are realized. New graphics display hardware and software may be used to provide virtually an “offthe-shelf”, and very cost-effective major system upgrade. Meanwhile, little modification to the host processor hardware or software system is required. This paper examines these premises, and discusses several examples of major Telemetry systems which have made this upgrade.

Network Telemetry: Practical Experiences and Unique Features

D’Amico, William P., Stadter, Patrick A., Lauss, Mark H., Hooper, Andrew 10 1900 (has links)
International Telemetering Conference Proceedings / October 21, 2002 / Town & Country Hotel and Conference Center, San Diego, California / The US Army’s Yuma Proving Ground (YPG) uses a wireless local area network (WLAN) to gather test data. It is desired to extend this WLAN to support tests of gun-launched munitions where miniature and rugged data acquisition hardware will be required. The Two Way Robust Acquisition of Data (2-RAD) program has been initiated under the Central Test and Evaluation Investment Program (CTEIP) to develop a process to expand the use of WLAN technology, which is now primarily used at YPG for internal ballistic test data acquisition.
