TLD

Long term object tracking is becoming more popular with the introduction of the Tracking-Learning-Detection TLD algorithm, and yet it has not been fully optimized to operate in scalable environments. It is essential to address some sections of the algorithm in terms of intense computations in order to cope the real-time requirements and boost the overall performance of object tracking. In this study, the core components of the algorithm that slow down the operation were investigated and implemented in parallel computational environments such as Multicore-CPUs and GPUs (graphics processing unit) with the use of OpenCL framework. Such implementations make it applicable for larger video inputs or higher frame-rates. The model then can be expanded to process multiple inputs simultaneously, and that parallelism brought speed up to the existing implementation. The implementation kernels are RGB to Gray, Sobel Filter and Variance Filter, and their performance evaluated similarly using different image sizes and implemented on different devices. According to the experimental results, for relatively small inputs the speed up for kernels is minimal, but it scales very nicely for large inputs. Speed ups are obtained as 2X for RGB to Gray conversion, 56.25X for Sobel Filter and 54.33X for Variance Filter.

One of the major reasons that website outages occur is based on issues with the secure socket layer (SSL) protocol. A key piece to this is many organizations now outsource their websites and often never attempt access to their company on a day to day basis via external resources. An example that most commonly occurs is when organizations forget to renew SSL certificates or auto renewing applications fail. Additionally, SSL insecurity can also occur when there are misconfigurations. The following is a foundational example of how to integrate real world failures into test, training and exercise events. Case Study: Service Outage Due to Mis-configured SSL Certificate BACKGROUND:

This paper reports on an investigation into the optically stimulated luminescence (OSL) properties of several known thermoluminescent materials, namely LiF:Mg,Ti, Li2B4O7:Cu, CaSO4:Tm, and CaF2:Mn. Samples were irradiated to air doses of 15 mGy, 150 mGy and 1.5 Gy and analyzed using a commercially available OSL reader system to determine their luminescence response to continuous blue and infrared light (IR) excitation, centered at 470 nm and 830 nm wavelengths, respectively. CaF2:Mn did not show an OSL response with either IR or blue light stimulation. Li2B4O7:Cu and LiF:Mg,Ti demonstrated relatively weak OSL signals only under blue light excitation. CaSO4:Tm exhibited OSL under both IR and blue light stimulation at sensitivities roughly one order of magnitude less than the OSL response of α Al2O3:C under the same conditions.

In this work the impact of reading out of the un-irradiated LiF TLDs based on the post irradiation readout was investigated. Four types of LiF detectors were used. The first three TLDs were MTS-N, MTS-6 and MTS-7 which differ only in the percentage abundance of Li 6 and Li 7 isotopes. The present results were discussed and compared with similar LiF (TLD-100, TLD-600 and TLD-700) fabricated by another company. MCP-N LiF dosimeters were also studied and compared with similar detectors of different only in the doping materials. The current results indicated that all of the LiF doped with Mg and Ti detectors were affected dramatically by the pre-irradiation readout process regardless of the fabrication companies. Otherwise, the impact of different doping materials was contradictious. These dramatic changes could be attributed to the occurrence of the nonradiative recombination through the irradiation process which yield high temperature peaks in the glow curve of the investigated LiF: Mg,Ti in contrary to LiF: Mg,Cu,P detectors.

This study examines the reproducibility of LiF:Mg,Ti pre-irradiation and post-irradiation fading rates. To test post-irradiation fading, 99 calibrated 3.2 × 3.2 × 0.9 mm3 LiF:Mg,Ti thermoluminescent dosimeters (TLDs) of dimensions were first annealed. The set was then irradiated to an average of 4.4 mGy using a 3.2 × 1011 Bq 137Cs source. The irradiated TLDs were allowed to fade at room temperature for 0.5, 1, 2, 3, 4, 8, or 17 d. The TLDs were then read out over a 3.5 h time period using a standard commercial hot planchet TLD reader with nitrogen gas to prevent chemiluminescence. The experiment was then repeated for the other fading times. To test pre-irradiation fading, the TLDs were annealed, then placed in storage for 0.5, 1.6, 3, 4, 8, 18, 27, or 43 d. After that time, the TLDs were irradiated and read out. A computerized glow curve deconvolution program was used to fit the glow curve data to a four-peak first-order Gaussian kinetics model. The areas of peaks 2, 3, 4, and 5 were retrieved in order to be studied alone, as well as normalized to other peaks. The peak areas and peak area ratios were then fit to two or three term exponential decay equations that allowed the determination of the fading rate by calculating their parameters. These parameters were then compared for different TLDs in order to determine if their values followed a Gaussian distribution. Then, a group mean and standard deviation could be used for each value for all TLDs for later use instead of calculating an individual mean for each TLD.

Thermoluminescent dosimeter (TLD) of carbon–doped aluminium oxide (α–Al2O3:C) produced in the form of single crystals show high sensitivity to ionizing radiation (about 40–60 times higher than TLD–100 (LiF:Mg,Ti)). The present article offers a review of the materials preparation and corresponding thermoluminescence (TL) properties of α–Al2O3:C subjected to various types of ionizing radiations. Different methods of α–Al2O3:C preparation in form of single crystal and thin films are reviewed. The development of methods of preparation is based on the approaches that involve the evaluation of the luminescence light yield in TL process. Most of the methods used were suitable, but each of these methods has their advantages and disadvantages depending on the required form of materials. Considering the results presented by various authors, possible better method of material preparation is proposed. The potential alternative fabrication technique of α–Al2O3:C thin film by using radio–frequenc...

In recent past fly ash is only being treated as waste and a source of air and water pollution but is in fact an eco-friendly and economically beneficial resource material for various applications and has also proven its worth over a period of time. The utilization of fly ash in several novel researches will also paves the path for systematic disposal of this waste material. The present paper involves the study of Thermoluminescence (TL) of different compositions of fly ash collected from National Thermal Power Corporation, Korba, Chhattisgarh, INDIA with (CaSO4:Dy) Phosphor. Thermo luminescence Dosimeters are regarded as the badge which absorbs the radiation when persons having TLD badges are exposed to radiation. We have to investigate and compare the glow curve behavior of pure phosphor and 10 %, 20 % and 30 % fly ash doped phosphor when it is exposed to gamma irradiation Cs 137 .

Implantable miniature thermoluminescent dosimeters and conventional biodistribution analysis were used to determine the locally absorbed radiation dose delivered to three morphologically distinct human renal cell carcinoma xenografts (TK-39, TK-82 and TK-177C; N = 87) following a 50 microCi infusion of 131iodine-labeled monoclonal antibody A6H. Xenografts were clearly detected by radioimmuno-scintigraphy. Pronounced differences were noted among the three xenografts in MAb pharmacokinetics and in the locally absorbed irradiation doses which ranged from 2 to 5 cGy per injected microCi of 131iodine-labelled A6H.
