In this letter, we provide a formal framework for comparing the expressive power of Behavior Trees (BTs) to other action selection architectures. Taking inspiration from analogous comparisons structural programming methodologies, formalise concept `expressiveness'. This leads us an expressiveness hierarchy control architectures, which includes BTs, Decision (DTs), Teleo-reactive Programs (TRs) ...

The basic concept adopted in the cellular code division multiple access (CDMA)-based navigation system proposed in [1] very much resembles the Differential Global Positioning System (DGPS). The proposed system setup employs CDMA base transceiver stations (BTS) with an auxiliary mapping receiver used for estimating the BTS clock biases. The estimated BTS clock biases and the pseudorange measurem...

This article presents a distributed antenna system (DAS) architecture for small-cell base stations (BTSs), whereby cooperation between the DAS infrastructure and the BTS allows for an increase in performance compared to conventional systems, while at the same time keeping complexity and cost at low levels. Specifically, the article investigates the improvements in uplink physical layer performa...

Definition of community acquired pneumonia (CAP) CAP can be defined clinically as the presence of signs and symptoms of pneumonia in a previously healthy child due to an acute infection (of less than 14 days’ duration) of the lower respiratory tract (usually occurs below terminal bronchioles) leading to cough or difficult breathing, tachypnoea, or lower chest-wall indrawing, which has been acqu...

High-frequency stimulation of skeletal muscle has long been associated with ionic perturbations, resulting in the loss of membrane excitability, which may prevent action potential propagation and result in skeletal muscle fatigue. Associated with intense skeletal muscle contractions are large changes in muscle metabolites. However, the role of metabolites in the loss of muscle excitability is n...

Overview The United States Department of Transportation’s Bureau of Transportation Statistics (BTS) is developing its confidentiality policy which is based on its legislative mandate (49 U.S.C. 111(i)) to protect individually identifiable information. Because the field of statistical disclosure limitation (SDL) research is still evolving, BTS wants to take advantage of the latest SDL research i...

چکیده: در این مقاله، یک آنتن جدید چهارتایی شکافی فشرده برای به­کارگیری در گیرنده­های gps ارائه شده است. ساختار آنتن از چهار عنصر تشعشعی شکافی نیم­طول­موج با یک نوار اتصال کوتاه تشکیل شده است که با اختلاف فازی 90 درجه نسبت به یکدیگر تغذیه می­شوند. ابعاد آنتن ارائه شده 3mm24î24î12 است که در مقایسه با بسیاری از آنتن­های ارائه­شده تاکنون بسیار کوچک­تر است. همچنین آنتن پیشنهادی دارای خلوص قطبش راست­...

It was the aim of the present study to test whey as protective protein for the sperm cell in the long-term boar semen preservation medium TRIXcell. Analyses of sperm cell motility using computer-assisted semen analysis (CASA) indicated that the whey protein Porex has a similar protective effect as bovine serum albumin (BSA) in maintaining viability of stored boar sperm. Boar sperm diluted in TR...

Based on a vast set of in situ data, a first comprehensive overview of the oceanographic characteristics of Baı́a de Todos os Santos (BTS) is provided. BTS is the second largest coastal bay in Brazil (maximum area of 1223 km2 and average depth of 9.8 m), and is located in the northeast Brazil, in the vicinity of Salvador city. The circulation inside the bay is mostly tidally driven and does not ...

For integrable equations which can be solved by the Inverse Scattering Transform, there exist Bäcklund transformations (BTs) [1]. These transformations were first discovered for the Sine-Gordon equation at the end of the 19th century. Usually they are treated as nonlinear superpositions, which allow one to create new solutions of a nonlinear evolution equation from a finite number of known solu...
