ACTION BASED FEATURES OF HUMAN ACTIVITY RECOGNITION SYSTEM

Human actions are uncountable and diverse in nature; each action has its own characteristics and nature. Moreover, actions are sometimes different and sometimes very similar. Thus, it is rather challenging to implement a system that is capable of recognizing all human actions. However, the problem of recognition can be made simpler if the system of recognition is built gradually. Firstly, a set of required actions must be selected and then each action must be studied and analyzed to determine the most distinctive features that remain similar if different subjects perform the same action. The concept of action-based features is proposed and validated in this article. The system still has the ability to be extended to recognize more actions, simply by including contextual features of any added action. Experimental results have shown an outperforming performance with 100% accuracy based on the evaluation of UTKinect Action Data Set.
QMATH14: Mathematical Results in Quamtum Physics – abstracts

Q ua nt um In fo rm at io n Abel Molina (University of Waterloo) Revisiting the simulation of quantum Turing machines by quantum circuits through the study of causal unitary evolutions. Joint with John Watrous Yao [1] proved that t ≥ n steps of a quantum Turing machine running on an input of length n can be simulated by a uniformly generated family of quantum circuits with size quadratic in t. We revisit the simulation of quantum Turing machines with uniformly generated quantum circuits, and present a new variant of the simulation method employed by Yao, together with an analysis of it. This analysis reveals that the simulation of quantum Turing machines can be performed by quantum circuits having depth linear in t, rather than quadratic depth, and can be extended to variants of quantum Turing machines, such as ones having multi-dimensional tapes. Our analysis is based on extending a method of Arrighi, Nesme, and Werner [2] that allows for the localization of causal unitary evolutions. Our extension proves that such localization can still be performed when the causality assumptions are weakened. More specifically, it considers unitary evolutions that do not necessarily act causally on all elements of the spaceH they act upon. Instead, the unitary evolutions we consider are only causal when restricted to a subspace that satisfies certain constraints in its relation to the local spaces that together (i.e. through their tensor product) constitute the space H.

Analysis of Viscoelastic Hydromagnetic Oscillatory Flow under Radiation and Slip Flow Effects with Concentration

This paper is aimed on the study of slip effects of an unsteady oscillating flow of a second order viscoelastic, incompressible and electrically conducting fluid passing an infinite vertical porous channel. The radiation effects are also considered which is induced in the system due to the high temperature difference of the walls. Further the flow is assumed under chemical reaction and applied magnetic field effects. The solutions are obtained for velocity, temperature and concentration fields from the governing equations of flow using perturbation methods. Also the variations in the respective fields are discussed using graphs for different physical parameters appeared during the non dimensionalization process which converts the system of non linear partial differential equations to linear partial differential equations. Further the skin friction and Schmidt number are calculated along with their amplitude and phase angle which are represented through the tables.
Characterization of a new BALL cell line with constitutional defect of the Notch signaling pathway

Notch signaling contribution to B-cell acute lymphoblastic leukemia (B-ALL) development is still under investigation. The serendipitous onset of B-ALL in a patient affected by the germinal Notch mutation-dependent Alagille syndrome allowed us to establish a B-ALL cell line (VR-ALL) bearing a genetic loss of function in components of Notch signaling. VR-ALL is a common-type B-ALL cell line, grows in conventional culture medium supplemented with 10% serum, and gives rise, once injected into immunodeficient NOG mice, to a mouse xenograft model of B-ALL. Exome sequencing revealed deleterious mutations in some components of Notch signaling, including Jagged1, Notch1, and Notch2. In addition, VR-ALL is sensitive both in vitro and in vivo to γ-secretase inhibitors (GSIs) as well as conventional anti-leukemic drugs. For all these reasons, VR-ALL may help to gain more insights into the role of Notch signaling in B-ALL. www.oncotarget. com Oncotarget, 2018, Vol. 9, (No. 26), pp: 18341-18350
Simulink Model Analysis of Modulation Technique of UWB , OFDM and CDMA for Different Parameter

With pace of time there is tremendous development in communication and on other hand as population increasing exponentially with time many severe traffic situations arises for example congestion problem, quality of service and cost also. A researcher always tries to resolve complexity of the system means system must be simple, cost effective and easy to use. In our dissertation research area is to compare different characteristics parameters of digital modulation technique so that a final conclusion can be made which technique is best one when we transmit data and finally it reach at destination with minimum bit error rate (BER). In base paper only CDMA technique is considered but in our dissertation work UWB and OFDM also considered. In our research paper we implemented simulation result CDMA, OFDM and UWB for different band pass technique for example BPSK, QPSK, QAM, 16 QAM, 64QAM, Calculate Transmitter and receiver message of CDMA, OFDM and UWB, Bit Error Rate, Signal-to-Noise ratio (SNR) and MSE Equalizer. Besides this our dissertation having multi input multi output (MIMO) antenna concept used. Earlier single antenna concept was used, now we use array of antenna to provide much efficient and good quality of service or we can say MIMO (Multi input Multi Output).
Letter on “ Geometric construction of modular functors from conformal field theory ” and “ Construction of the Reshetikhin-Turaev TQFT from conformal field theory ” by

By the present letter, I wish to point out a subtlety in the definition of modular functor which appears in the papers [AU07, AU15] of Jørgen Andersen and Kenji Ueno. This affects the main result of [AU15] because the authors assume (in [AU15, Def. 4.1]) that their definition is equivalent to the one in [Tur94], whereas this is most likely not the case. After adopting a better definition, I expect the proofs in [AU07, AU15] to survive the necessary modifications, and to remain mostly unchanged. Andersen and Ueno attribute their definition to Kevin Walker [Wal91]. But the two definitions are actually not equivalent: one of the axioms which is implicitly present in [Wal91] has been dropped from [AU07, AU15]. I will argue that this makes the Andersen–Ueno definition too weak. On the other hand, the definition in [Wal91] is known to be too strong (it does not allow for anti-symmetrically self-dual objects, a fact pointed out in e.g. [Wan10, Chapt. 5]). The WZW modular functors V N,K constructed in [AU07] are therefore not modular functors in the sense of [Wal91]. The problem is therefore quite subtle. I propose an alternative definition of modular functor that lies strictly in between those of Andersen–Ueno and of Walker, but which retains the same spirit. It is obtained by replacing the axiom (1) of [Wal91] by the modified axiom (5). It is very likely that, after including that modified axiom, the notion becomes equivalent to the definition in [BK01, Def. 5.7. 10]. If this is true, then
One-Shot Voice Conversion with Disentangled Representations by Leveraging Phonetic Posteriorgrams

We propose voice conversion model from arbitrary source speaker to arbitrary target speaker with disentangled representations. Voice conversion is a task to convert the voice of spoken utterance of source speaker to that of target speaker. Most prior work require to know either source speaker or target speaker or both in training, with either parallel or non-parallel corpus. Instead, we study the problem of voice conversion in nonparallel speech corpora and one-shot learning setting. We convert an arbitrary sentences of an arbitrary source speaker to target speakers given only one or few target speaker training utterances. To achieve this, we propose to use disentangled representations of speaker identity and linguistic context. We use a recurrent neural network (RNN) encoder for speaker embedding and phonetic posteriorgram as linguistic context encoding, along with a RNN decoder to generate converted utterances. Ours is a simpler model without adversarial training or hierarchical model design and thus more efﬁcient. In the subjective tests, our approach achieved signiﬁcantly better results compared to base-line regarding similarity.
Barriers to the identification of occupational asthma

Occupational asthma (OA) is associated with an estimated annual societal cost in the UK of £100 million, which is avoidable if workers are identified quickly and removed from exposure to a sensitizing agent. The aim of this work was to identify barriers to diagnosing OA on the part of workers and healthcare professionals. The first study evaluated current practice in assessing working-age asthmatics for OA in a West Midlands primary care population. There was poor enquiry regarding occupation (14% of cases) and the effect of work on asthma symptoms (2%). The second study used qualitative methodology to explore beliefs and behaviours in symptomatic workers. Major influences on workers’ health seeking behavior were (1) understanding of their symptoms, (2) working relationships, (3) course of action with symptoms and (4) negotiation with healthcare professionals. The third study defined the important barriers from the point of view of healthcare professionals. Low awareness and adherence to OA guidelines was evident in all non-specialist groups. The fourth study evaluated the feasibility of introducing an electronic OA screening-tool for primary care. Healthcare professionals who used the tool found it to be quick and easy to implement and user-friendly, without impacting on the length of a consultation.
Design of High Speed Power Efficient Combinational and Sequential Circuits Using Reversible Logic

This Reversible logic has presented itself as a prominent technology which plays an imperative role in Quantum Computing. Quantum computing devices theoretically operate at ultra-high speed and consume infinitesimally less power. Research done in this paper aims to utilize the idea of reversible logic to break the conventional speed-power trade-off, thereby getting a step closer to realise Quantum computing devices. To authenticate this research, various combinational and sequential circuits are implemented such as a 4-bit Ripple-carry Adder, (8bit X 8-bit) Wallace Tree Multiplier, and the Control Unit of an 8-bit GCD processor using Reversible gates. The power and speed parameters for the circuits have been indicated, and compared with their conventional non-reversible counterparts. The comparative statistical study proves that circuits employing Reversible logic thus are faster and power efficient. The designs presented in this paper were simulated using Xilinx 9.2 software. Key Words— Reversible logic, Quantum Computing, high-speed, less power, speed-power trade-off, Ripple carry adder, Wallace tree multiplier, GCD processor, non-reversible counterparts.
The challenges of using polyethylene passive samplers to determine dissolved 1 concentrations of parent and alkylated PAHs under cold and saline conditions 2 3 Reitsma

10 Passive samplers can be useful tools to determine truly dissolved concentrations of organic 11 contaminants in the water. Polyethylene (PE) samplers were validated for measuring polycyclic 12 aromatic hydrocarbons (PAHs), with a focus on alkylated PAHs that can dominate in an oil spill. 13 Equilibrium partition coefficients (KPEw) between water and PE passive samplers were measured 14 for 41 PAHs both at ambient conditions (20 °C, no salt), down to -15 °C and 245 psu present in 15 ice brine. For each additional alkylated carbon, log KPEw increased by an average of 0.40 (± 0.20) 16 log units, close to predictions. The increase per aromatic carbon was only 0.33 (± 0.02) log units. 17 Apparent PE-water distributions of pyrene and deuterated pyrene (performance reference 18 compound) were within 0.1 log unit for all experiments at 20 and 2 °C, but started to diverge by 19 0.8 log units (-4 °C, 100 psu) and 3.1 log units (-15 °C, 245 psu). The delay in equilibrating 20 PAHs in these experiments was dominated by increases in the water’s viscosity, which in turn 21 affected both the PAHs’ aqueous diffusivity and the thickness of the water boundary layer.

A Hybrid Model of Student‐Centered Instruction Improves Physical Therapist Student Performance in Cardiopulmonary Practice Patterns by Enhancing Performance in Higher Cognitive Domains

Background and Purpose. Studentcentered instruction is prevalent in professional (entry‐level) physical therapist education programs. Previous studies in health care professions have suggested student performance may be enhanced with a student‐centered approach when compared to traditional lecture‐based instruction. The purpose of this study was to compare overall student test performance, test question performance in different cognitive domains, and preference to mode of instruction between a hybrid model of student‐centered and traditional lecture‐based instruction. Subjects. A total of 65 students in their third semester of a Doctor of Physical Therapy (DPT) degree program and who were enrolled in a 3‐credit cardiopulmonary practice patterns course participated in this study. Model Description. Subjects attended 6 classes during the first module of the cardiopulmonary practice patterns course. Three classes were taught using traditional lecture‐based instruction and 3 via a hybrid model of student‐centered instruction consisting of electronic lectures and small‐group, problem‐solving activities. After completion of the 6 classes, students were given a written test consisting of multiple choice and short answer questions within the knowledge, comprehension, analysis, and evaluation cognitive domains, and a survey regarding preferred mode of instruction. Outcomes. Student performance was 10.4% (95% confidence interval [CI], 6.5%‐14.3%) higher on test questions relating to the content taught via hybrid student‐centered instruction compared to traditional lecture‐based instruction (P < 0.001). More detailed analysis demonstrated that hybrid student‐centered instruction improved test performance over traditional lecture‐based instruction on questions within the higher cognitive domains of comprehension, analysis, and evaluation, but not on questions assessing knowledge (all P < 0.05). There were no differences in student preference for mode of instruction, with 43.1%, 24.6%, and 32.3% preferring traditional lecture‐based instruction, hybrid student‐centered instruction, and having no preference, respectively (P = 0.19). Discussion and Conclusion. The results of the study suggest that the hybrid model of student‐centered instruction improves the professional physical therapist student's test performance in a cardiopulmonary practice patterns course over traditional lecture‐based instruction. In particular, the hybrid student‐centered approach improved performance on higherorder level of questions, which fits with professional practice expectations. Students showed no preference for mode of instruction, confirming that learning style is very individual.
Acoustic Properties of Foreigner Directed Speech

The acoustic properties of vowels in clear speech have been extensively investigated, but a less explored area is that of foreigner directed speech (FDS). This study examined the production of Arabic /iː/, /uː/, /aː/ in the speech of 22 native Omani speakers, either addressing their foreign domestic helpers (FDH) or a native speaker (NS). Words containing the target vowels were elicited using an interactive spot the difference task. Vowel space, F1 and F2 measures, F0, intensity and duration were compared in productions to FDH and NS interlocutors. Speech to FDHs yielded higher F1, greater vowel space expansion and higher pitch and intensity than speech directed to the NS, but the differences were modest and there was no effect on F2. Moreover, vowels in speech to FDHs were surprisingly shorter in duration than those in speech to the NS. External factors relating to the peculiarity of the FDH context are considered.
Training Future Teachers to Develop Conscious Self-Regulation of Voluntary Activities

One of the most important psychological factors of efficient educational process is the ability of the teacher to consciously regulate their voluntary activities: for instance, their behaviour, their communication etc. In this respect, developing this kind of skill in students (teachers-to-be) during their university course appears to be of vital importance. The present paper is aimed at sharing the results obtained within the framework of the conducted experiment. The main objective of the latter was to implement the programme of training future teachers to develop their conscious self-regulation of voluntary activities. The theoretical approaches used in the research were the analysis of other psychological and educational surveys on the subject under study, induction, deduction and modelling. Observation, testing and educational experiment were used as empirical approaches to the survey. The major technique used in the research was “The Style of Behaviour Self-Regulation (SBSR)” designed by V.I. Morosanova. While processing the information concerning the results of the survey we used techniques of quantitative and qualitative data analysis. Mathematical and statistical data processing was performed by means of “SPSS Statistics 17.0” service pack.
Aalborg Universitet Descriptors of server capabilities in China cases of multinational companies

China with the huge market potential it possesses is an important issue for subsidiaries of western multinational companies. The objective of this paper is therefore to strengthen researchers’ and practitioners’ perspectives on what are the descriptors of server capabilities. The descriptors are relevant to determine subsidiary roles and as an indication of the capabilities required. These descriptors are identified through extensive literature review and validated by case studies of two Danish multinational companies subsidiaries operating in China. They provided the empirical basis for this paper. The characteristics of the subsidiaries were analyzed and the results suggest a number of descriptors of server capabilities.
ETHANE PRODUCTION PLANT FOR BETTER ENERGY INTEGRATION AND COST REDUCTION IN JORDAN

The recovery of ethane from natural gas is considered to be more economically feasible due to shift in ethane prices and advances in process modifications. Process design and retrofitting of ethane recovery technologies are reviewed. A viable process design for the production of ethane using Qatari natural gas as feedstock in Jordan is proposed. The plant capacity is determined to be 8.83*109 scf per year at purity of 98.6 percent. Process design and energy integration are performed using CHEMCAD and HENSAD simulation software. The optimal process flow diagram (in terms of energy integration) consists of three major sections: Pretreatment section, liquefaction and cryogenic separation of methane and ethane. By using parametric studies, the major operating and design variables are optimized. The simulation results show that the ethane recovery plant proved be able to produce ethane and methane as a byproduct at a purity up to 98.6 and 99.7, respectively. Moreover, preliminary economic evaluation (profitability analysis) based on discounted and not discounted methods is performed. It results in an average ROROI of 16 percent value, and a nondiscounted payback period of 4.5 years.
Evaluating the Degree of Randomness in Optical Quantum Random Number Generators

Quantum random number generators are used today in a variety of applications; mainly for stochastic simulation and secure communications. As these fields grow, fast and convenient random number generators that generate truly random number sequences are sought for. The aim of this study is therefore to build different kinds of optical quantum random number generators and evaluate their degree of randomness. The setups studied all depend on quantum indeterminism. A laser beam was divided in different ways, and the path the photons took was registered and converted to a binary sequence. Four different experimental setups were studied. To divide the beam, a 50/50 beam splitter, a H/V polarized beam splitter and a two path fiber coupling was used. The two path fiber coupling was further divided into two separate experiments, one using a field programmable gate array for data collection and one using a time tagging unit. The two correlation algorithms used to test for randomness in the strings fount that the two path fiber coupling method with a time tagging unit for data collection generates random number sequences with the highest degree of randomness in the study. Its random number sequences also passes the randomness test suite of The American National Institute of Standards and Technology (NIST).
