background: intraoperative radiation therapy (iort) technique is used to treat a surgically exposed tumor or tumor bed in the treatment of locally advanced intraabdominal, retroperitoneal, pelvic, thoracic, breast and soft tissue tumors. one way to perform iort is to use an existing linac and modify the treatment head using an applicator system. in this study the objectives were to design, and ...

Small and micro enterprises have a decreasing participation in vocational education and training. There is a real need to engage them in developing a positive attitude towards training. The BOOST (Business perfOrmance imprOvement through individual employee Skills Training) project will integrate outcomes from two previous projects (BECOME and ROLE), in order to develop associated methodologies...

This paper deals with mainly the profoundly deaf people who are beginning to learn the British Sign Language (BSL) as their first language for communication. These beginners could be children, teenagers or even adults who have hearing problems. There are already quite a few BSL learning websites and Lip Reading software available on the market. However, there is no such software that associates...

in this paper the maximum power point tracking (mppt) algorithms for wind energy systems arereviewed. as the amounts of power produced in wind power plants is changing due to theinstantaneous changing nature of the wind, it is desirable to determine the one optimal generatorspeed that ensures maximum energy yield. thus, it is important to include a controller that cantrack the maximum peak rega...

This paper presents an implementation of open loop and closed loop control of Quadratic boost converter using PID controller.  Quadratic boost converter consists of boost converter and fly back converter driven by a single switch. Quadratic boost converter QBC is designed especially for regulating the DC interface between various micro sources and dc-ac inverter to electricity grid. Quadratic b...

Computational results demonstrate that posterior sampling for reinforcement learning (PSRL) dramatically outperforms existing algorithms driven by optimism, such as UCRL2. We provide insight into the extent of this performance boost and the phenomenon that drives it. We leverage this insight to establish an ̃ O(H p SAT ) Bayesian regret bound for PSRL in finite-horizon episodic Markov decision ...

Under-resourced speech recognizers may benefit from data in languages other than the target language. In this paper, we boost the performance of an Afrikaans speech recognizer by using already available data from other languages. To successfully exploit available multilingual resources, we use posterior features, estimated by multilayer perceptrons that are trained on similar languages. For two...

background: the purpose of this study was to evaluate nodal irradiation with conventional three-field's technique. materials and methods: fifty patients with breast cancer were enrolled in this study. computed tomography scans in the supine treatment position were imported into a treatment planning system. levels i-iii axillary and supraclavicular nodes were identified and their depths to ...

the field of vaccinology provides excellent promises to control different infectious and non-infectious diseases. genetic immunization as a new tool in this area by using naked dna has been shown to induce humoral as well as cellular immune responses with high efficiency. this demonstrates the enormous potential of this strategy for vaccination purposes. dna vaccines have been widely used to de...
