Millimeter wave (mmWave) based sensing is a significant technique that enables innovative smart applications, e.g., voice recognition. The existing works in this area require direct of the human's near-throat region and consequently have limited applicability non-line-of-sight (NLoS) scenarios. This paper proposes AmbiEar, first mmWave recognition approach applicable NLoS AmbiEar on insight cau...
The paper addresses the problem of line-of-sight (LOS) vs. non-line-of-sight (NLOS) propagation link identification in ultrawideband (UWB) wireless networks, which is necessary for improving the accuracy of radiolocation and positioning applications. A LOS/NLOS likelihood hypothesis testing approach is applied based on exploiting distinctive statistical features of the channel impulse response ...
abstract poor reading comprehension can result in failure in using references, benefiting from professional gatherings and resources, keeping up with the growing body of knowledge in the virtual world of the internet, and failing to achieve in efl programs. the purpose of the present quasi-experimental study was to explore the effects of background knowledge and previewing narrative and expos...
in chapter 1, charactrizations of fragmentability, which are obtained by namioka (37), ribarska (45) and kenderov-moors (32), are given. also the connection between fragmentability and its variants and other topics in banach spaces such as analytic space, the radone-nikodym property, differentiability of convex functions, kadec renorming are discussed. in chapter 2, we use game characterization...
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
Light-fidelity (LiFi) is a fully-networked bidirectional optical wireless communication (OWC) technology that considered as promising solution for high-speed indoor connectivity. In this paper, the joint estimation of user 3D position and equipment (UE) orientation in LiFi systems with unknown emission power investigated. Existing solutions problem assume either ideal system settings or perfect...
In this paper, an efficient model of the channel matrix is developed for 2 × Wireless Body Area Network Multiple Input Output (WBAN-MIMO) system, based on deep learning algorithms. The composed three Moreover, predicts simultaneously H in underground mine and identifies position collected data both Line Sight (LoS) Non-Line (NLoS) scenarios. trained evaluated using magnitude phase...
چکیده : آرای صادره از دادگاه ها علاوه بر شیوه های عادی از طریق فوق العاده نیز قابل اعتراض و رسیدگی مجدد هستند. در مواقعی که رای دادگاه مخل به حقوق ثالث باشد وی می تواند به ان اعتراض کند. قلمرو شمول اعتراض ثالث به تصمیمات قضایی که از آن به رای تعبیر شده محدود می گردد. ولی در مورد قرارها که به اعدادی و نهایی تفکیک می شوند، چون هیچ رویه ثابت و مشخصی در این زمینه در دادگاهها وجود نداشته و همچنین ا...
abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
there are many approaches for solving variety combinatorial optimization problems (np-compelete) that devided to exact solutions and approximate solutions. exact methods can only be used for very small size instances due to their expontional search space. for real-world problems, we have to employ approximate methods such as evolutionary algorithms (eas) that find a near-optimal solution in a r...
