TP 1 P Relationship between Wingate test and vertical jump in young female volleyball players

condition. Results: The one-year prevalence of neck pain was 42.9 %. Multivariate analysis revealed that pilots instructor have right side rotation limited (-9.4 vs. non instructors, F1,36 = 8.6 with p\ 0.01). The use of head-mounted system (HMS) did not affect ACROM and muscular functionality. There were significant differences between Neck Pain Group (NPG) and healthy group of pilots concerning some ACROM (p\ 0.05) and some MEP (p\ 0.05). In NPG the levels of perceived pain showed significant correlation with past flight experience parameters (p\ 0.05) and the years of flight career (p\ 0.05). The amount of core stability activities, ball games, and weight lift exercise, negatively correlated with the level of perceived pain (p\ 0.05). Conclusion: ACROM and MEP were worst in NPG. The past flying experience on high-performance aircraft such as the F16 was highly related to neck pain. The negative correlation of some physical activities may suggest to further investigate their role in preventing the neck pain in EFA pilots.

Effects of Shared Leadership Perception on Perceived Intragroup Conflict: An Investigation in Technology Startups in Turkey

Though research about antecedents of competitiveness reveals many factors, a common ground appears to be teamwork. Keeping this in mind, this study considers teamwork, but goes one step further by addressing what lies beneath teamwork: collectivism. A review about collectivist notion in groups’ points out that intragroup conflict, and management and leadership are the two outstanding determinants of group effectiveness. A further outcome from the review is that shared leadership is also emphasized within this notion. Therefore, this study investigates if and how shared leadership perception is effective on perception about intragroup conflict. The research, performed in technology startups in a techno park in the city of İstanbul, reveals noteworthy results. There is a similarity between the structures of perceived shared leadership and intragroup conflict perception in the way that both emphasize their own formal and informal components distinctively. The findings also prove that the participants’ perceived intragroup conflict changes based on their perception towards shared leadership. This change, nevertheless, is not fully possible when the attention turns from the macro level to the factor level.
IAA-AAS-DyCoSS2-14 -02-05 TERMINAL ATTITUDE-CONSTRAINED GUIDANCE AND CONTROL FOR LUNAR SOFT LANDING

This work concentrates on a 3-dimensional guidance and control (G&C) scheme for the terminal landing phase of a lunar spacecraft. In order to cope with terminal attitude constraints, we take the commanded acceleration as an extended state whose terminal value relates to the terminal attitude constraints. Then in optimal control framework, an optimal terminal attitude-constrained feedback guidance law is derived. In order to accommodate various disturbances, a finite-time convergent extended state observer is utilized to estimate the disturbance. Driven by the disturbance observer, an improved sliding mode controller with a disturbance compensation is proposed. The attitude tracking error signals theoretically prove to be ultimately uniformly bounded. The convincing simulation results reveal the excellent performance is achieved by the proposed method during the terminal landing phase.
Genotyping of A251g, Copper-Zinc Superoxide Dismutase (Cuznsod) Polymorphism, in Term Pregnant Women In Uyo, South-South, Nigeria

Cu/ZnSOD protein and its gene are located on chromosome 21q22. Cu/ZnSOD is found almost exclusively in intracellular cytoplasmic spaces and comprises 90% of total SOD making the investigation of Cu/ZnSOD expression levels has become very important. The A251G Copper-Zinc Superoxide Dismutase polymorphism is distributed widely among south -south pregnant Nigerian population, showing the prevalence of the wild type. Fifty apparently healthy subjects were recruited from St. Luke’s Hospital Anua, Akwa-Ibom State, Nigeria during the antenatal clinic. Genotyping of A251G polymorphism was done using polymerase chain reaction (PCR) followed by restriction digestion (RFLP) using MspI( Moraxella species), an Isoschizomer of HpaII.The study shows 64.10 % were wild type, 25.64 % were heterozygous and 10.26 % were homozygous for A251G CuZnSOD polymorphism. The A allele frequency which was used as the reference allele was the most common,75%, while the least common was the G allele,25%,which was used as the variant. This study was prompted by the absence of published data on the prevalence of A251G CuZnSOD polymorphism in Nigeria.
Formulation and In Vitro Evaluation of Casein Nanoparticles as Carrier for Celecoxib

Purpose: The objective of this work was to formulate casein (CAS) nanocarriers for the dissolution enhancement of poorly water soluble drug celecoxib (CLXB). Methods: The CLXB loaded CAS nanocarriers viz., nanoparticles, reassembled CAS micelles and nanocapsules were prepared using sodium caseinate (SOD-CAS) as a carrier to enhance the solubility of CLXB. The prepared formulations were characterized for particle size, polydispersity index, zeta potential, percentage entrapment efficiency, and surface morphology for the selection of best formulation. Fourier transform infrared spectroscopy, differential scanning calorimetry and X-ray powder diffraction study was used to for the confirmation of encapsulation of CLXB. Further,in vitro drug dissolution, ex-vivo permeation studies on chicken ileum and stability studies were carried out. Results: The CLXB loaded casein nanoparticles (CNP) (batch A2) showed a particle size diameter 216.1 nm, polydispersity index 0.422 with percentage entrapment efficiency of 90.71% and zeta potential of -24.6 mV. Scanning electron microscopy of suspension confirmed globular shape of CNP. Thein vitro release data of optimized batch followed non Fickian diffusion mechanism. The ex vivo permeation studies on chicken ileum of CLXB loaded CNP showed permeation through mucous membrane as compared to pure CLXB. The apparent permeability of best selected freeze dried CLXB loaded CNP (batch A2) was higher and gradually increased from 0.90 mg/cm2 after 10 min to a maximum of 1.95 mg/cm2 over the subsequent 90 min. A higher permeation was recorded at each time point than that of the pure CLXB. Conclusion: The study explored the potential of CAS as a carrier for solubility enhancement of poorly water soluble drugs.

THEORETICAL ANALYSIS OF THE FAR-FIELD DIRECTIONAL ACTIVE NOISE CONTROL

The traditional active control of the quiet zone is to control the noise in a relatively constrained area within the sound field. In this paper, the concept of the quiet zone has been extended to the active control of the directional far-field of noise sources. The noise field generated by those noise sources like power transformer plant, which may have complex characteristics in the near-field, would approach spherical wave or plane wave in the far-field with so-called directivity pattern. A novel active control strategy, the far-field directional active noise control method, is proposed to cancel the noise in the far-field of the noise sources in some specific directions based on the wave front synthesis method. It is shown in theoretical analysis and numerical simulation that the proposed method can improve the control performance in enlarging the quiet zone while reducing the unwanted the noise produced by the control system outside the target area.
A High-Performance Online Uninterruptible Power Supply (UPS) System Based on Multi- task Decomposition

High quality online uninterruptible power supplies (UPS) are widely used in applications e.g. precision medical equipment with critical loads. This paper proposes a low-cost and high performance online UPS system. Firstly, the performance improvement of a bidirectional switch based bridgeless power factor (PFC) converter, which is regulated by a hybrid control strategy with load current feedforward is studied. Secondly, the proposed closed-loop controller integrates improved predictive current control with predictive voltage control and applies to the second-stage neutral-point-clamped (NPC) three-level inverter for low output voltage harmonics. Moreover, a push-pull dc-dc converter interfaces and boosts voltage of a 24V battery bank as the backup energy source. Considering complexity of the UPS system as well as cost reduction, we implement a multi-task decomposition method for control on a monolithic low-cost digital signal processor (DSP) embedded with Control Law Accelerator (CLA). Finally, the experimental results from a 1kVA a prototype can effectively verify validly of the theoretical analysis and design.
ARDL Modeling of the Impact of Financial Reforms on Private Domestic Saving in Cameroon

The aim of this study is to model the effects of financial sector reforms on private domestic savings in Cameroon. After building an econometric model of private domestic savings from the theory of financial repression of McKinnon and Shaw (1973), it is analyzed using ARDL co integration approach. The results indicate that there exist a long run negative and significant relationship between private domestic savings and financial reforms. In the short run, this relationship is positive though not significant. On the basis of these results, we recommend that Cameroonian authorities, in their quest for growth and prosperity for the country, should envisage revising the ongoing liberalization process in the country.
An efficient recommender system approach for collaborative filtering

: Many companies are used recommender system to give basic knowledge and feedback information about product and service to the customers. Generate the recommendations based on the likes usage history and preferences. Collaborative filtering generates recommendation by using the previous recommendations of other users. The collaborative filtering is the basic idea for analysis and customer behaviour from the past history that gives the future prediction that may like similar items. When process the large amount of data that old and previous recommender techniques are not efficient for sparsity, efficiency and scalability. Single node machines are the time consuming on large data sets. Parallel distributed file filtering model (PDFM), The PDFM recommender system is working on parallel files for MapReduce framework and uses correlation as similarity metric. Parallel distributed file filtering model (PDFM) allows distributed processing of big data across multiple clusters of nodes.
Survey of Wi-Fi Trash Bin

: This paper uses the concept of Automation used in the domain of Public Cleanliness and Hygiene. Careless trashing of garbage onto the roads is a common scenario to be found in all developing countries. A Wi-Fi Trash Bin is a concept of an attached Wi-Fi router along with a dustbin. Whenever anyone puts the trash in the dustbin, it automatically detects that trash and generates a temporary Wi-Fi code for the user to connect to free Wi-Fi for a limited period of time. Once the time limit is over it automatically disconnects the user. A single user can use the Wi-Fi twice a day. A Wi-Fi Trash Bin uses multiple technologies. The first is Wi-Fi technology which we have to optimize to make sure that all the generated codes work properly. The second technology used for motion sensing and figuring out how the trash comes in and its movement. The third is entire bridge between the motion sensor and the Wi-Fi network to ensure that they connect at the right time. So it is a mix of hardware and software technologies. Wi-Fi dustbin is a new concept where users get awarded (free Wi-Fi connectivity) for keeping their surroundings clean. We got inspired from “Swachh Bharat Abhiyan” which is a national campaign by the Government of India, to clean the streets, roads and infrastructure of the country. Citizens are now becoming active participants in cleanliness activities across the nation; the dream of a Clean India once seen by Mahatma Gandhi has begun to get a shape.
NEAR-FIELD ERROR SENSING OF MULTI-CHANNEL ACTIVE NOISE CONTROL USING VIRTUAL SENSING TECHNIQUE

This paper proposes a near-ﬁeld error sensing method for multi-channel feedforward active noise control (MCFFANC). The proposed method is particularly useful in applications such as the active noise canceling window that can mitigate noise passing through an open window. In MCFFANC, the classic multiple-error LMS algorithm is derived for minimizing the sum of the squared errors, which is an appropriate approximation of the noise power when the error microphones are placed in the far ﬁeld. However, owing to the room reverberation, the error microphones are preferably placed in the near ﬁeld. Therefore, there is a mismatch between the algorithms and applications of MCFFANC. Near-ﬁeld error sensing methods are desired in MCFFANC. For such purposes, this paper extends the single-channel virtual sensing technique to the multiple-channel case. The effectiveness of the proposed method is validated by an experimental setup of the active noise can-celing window. An improved global reduction of noise is conﬁrmed at far-ﬁeld observation points.
Enhancement of Power Quality in Distribution System Using D-STATCOM

In this paper a new algorithm is proposed for a DSTATCOM operating in voltage control mode to generate reference voltage. The proposed scheme ensures that unity power factor (UPF) is achieved at the load terminal during nominal operation, which is not possible in the traditional method. The compensator here is also used to inject lower currents so that the losses in the feeder and VSI are reduced. Further rating of DSTATCOM can also be reduced so that it mitigates the voltage sag. Nearly UPF can be maintained at the load terminal during load change. Due to the above reasons the DSTATCOM increases the power quality by improving power factor, harmonic reduction, and tight voltage regulation. Simulation results are presented to determine the efficiency of the proposed algorithm of DSTATCOM.
Geometric Jacobian linearization

For control systems that evolve on Euclidean spaces, Jacobian linearization is a common technique in many control applications, analysis, and controller design methodologies. However, the standard linearization method along a non-trivial reference trajectory does not directly apply in a geometric theory where the state space is a differentiable manifold. Indeed, the standard constructions involving the Jacobian are dependent on a choice of coordinates. The procedure of linearizing a control affine system along a non-trivial reference trajectory is studied from a differential geometric perspective. A coordinate-invariant setting for linearization is presented. With the linearization in hand, the controllability of the geometric linearization is characterized using an alternative version of the usual controllability test for time-varying linear systems. The various types of stability are defined using a metric on the fibers along the reference trajectory and Lyapunov’s second method is recast for linear vector fields on tangent bundles. With the necessary background stated in a geometric framework, Kalman’s theory of quadratic optimal control is understood from the perspective of the Maximum Principle. Finally, following Kalman, the resulting feedback from solving the infinite time optimal control problem is shown to uniformly asymptotically stabilize the linearization using Lyapunov’s second method.
Drug history errors in the acute medical assessment unit quantified by use of the NPSA classification

Results A pharmacist and pharmacy technician reviewed 200 acute medical patients. 123 patients had at least one discrepancy noted when comparing the medication prescribed in AMAU with the medicines taken before admission. A total of 234 errors were recorded with an average of 1.9 errors per patient. When assessed (independently by four health professionals) against the NPSA risk assessment tool, 185 (79%) were perceived as only of minor consequence, 46 (20%) as moderate and 1 (0.4%) as being potentially of major consequence.

Entrepreneurial Production Function and Firm Dynamics Preliminary

The objective of this paper is to understand the role of business owners' working hours in the production of their rms. We use a novel dataset on US start-ups to show that their owners work non-neglible hours, which correlate strongly with the rmlevel output and employment. In order to interpret better the empirical evidence, we study an entrepreneurial production function that parametrizes the role of owners' hours into the degree of substitutability/complementarity they have with the hired labor. The calibration of the model to match important empirical features suggests large substitutabilities between owners' hours and their hired labor. We show that hours adjustments of owners can be crucial in coping with the nancial constraints, and omitting these can lead to a substantial overstatement of the impact of nancial frictions on rms' life-cycle pro les.

Ecology and Phenology of Flowering Rush in the Detroit Lakes Chain, Minnesota

Flowering rush, Butomus umbellatus, has been an increasing problem in the Detroit Lakes chain of lakes for more than 45 years. Flowering rush dominates ecosystems by crowding out native species including hardstem bulrush, Schoenoplectus acutus; a vital part of native ecosystems. 5 Furthermore, flowering rush creates boating hazards and hampers recreational activities on the lakes. The phenological differences between flowering rush and the native hardstem bulrush were examined as part of a project determining the best management practices for controlling this invasive species. Biomass allocation, plant height, carbohydrate allocation and reproductive structures of flowering rush were examined in the Detroit Lakes system. Flowering rush and 10 hardstem bulrush exhibited similar times of emergence, maximal growth and senescence, First, third, and fifth authors: Professor, and Undergraduate Students, Biology Department, Concordia College, Moorhead, MN 56562; Second and fourth authors: Professor and Graduate Student, Geosystems Research Institute, Mississippi State University, Mississippi State, MS 39762-9627.

High efficiency adjustable speed control of IPMSM with variable permanent magnet flux linkage

An interior permanent magnet synchronous motor (IPMSM) with variable permanent magnet flux linkage is introduced in this paper. By adapting movable flux-shortening iron pieces in the flux barriers of the rotor, it is possible to decrease the permanent magnet flux linkage to some extent. In the flux-weakening control region, the required d-axis current to weaken the armature flux linkage becomes smaller due to the decrease of the permanent magnet flux linkage. The constant output power operating range of the proposed IPMSM can be extended compared to the conventional IPMSM under the same limitation of the supply ability of the inverter. The becoming smaller d-axis current also contributes to the improvement of the efficiency as well as the power factor characteristics especially at light load, high speed operation. By choosing suitable inserting scheme of the movable iron pieces, it is possible to realize optimal operating performance for the proposed IPMSM. The advantages of the IPMSM proposed in this paper are verified with experiments.
PASSWORD CRACKING BASED ON LEARNED PATTERNS FROM DISCLOSED PASSWORDS

Password-based authentication systems are still the most commonly used mechanism for protecting sensitive information despite being vulnerable to dictionary based attacks. To guard against such attacks, many organizations enforce complicated password-creation rules and require that passwords include numeric and special characters. This study demonstrates that as long as passwords are not diﬃcult to remember, they remain vulnerable to \smart dictionary" attacks. In this study, a password analysis platform is developed to formally analyze commonly used passwords and identify frequently used password patterns and their associated probabilities. Based upon these patterns, we establish a model consisting of a Training set, a Dictionary set and a Testing set (TDT model) to generate probabilistic passwords sorted in decreasing order. The model can be used to dramatically reduce the size of the password space to be searched. Simulation results show that the number of passwords cracked using the TDT model is 1.43 and 2.5 times higher compared with the John-the-Ripper attack and Brute-force attack, respectively. We also design a hybrid password cracking system combining diﬀerent attacks to verify the eﬀectiveness of the proposed method. After applying the TDT model, the number of passwords cracked increased by up to 273%.
