Residential Property Valuations near Transit Stations with Transit Oriented Development
Year: 2014

Access to train stations is highly valued and this is reflected in the premium price of residential property near train stations. Transit oriented development (TOD) and the amenities provided by mixed use development may also provide value to consumers. The analysis presented here evaluates the average property valuations surrounding eight transit stations with TOD using residential property valuation data provided by Zillow(tm) an on line real estate listing firm. An hedonic regression analysis evaluates the association between average block level residential property valuations and the distance to the station with TOD and other stations with direct access to New York City. Results suggest that while the mixed use development typically found with TOD is likely valued, proximity to stations with direct access to New York City leads to higher relative property valuations.
A discussion about choosing an objective function and constraint conditions in structural topology optimization
Year: 2013

1.  Based on some examples calculated using the 99 line code made by Sigmund  the structural topology optimization model construction is discussed to propose a problem that whether the topology optimization model construction could be more reasonable. In order to solve this problem, a topology optimization model according to practical engineering is constructed to search for the minimization of structural weight with a displacement constraint. And a corresponding 120 line code written in Matlab is made by us. Calculation results of the examples show that the model of the 120 line topology optimization code is more reasonable. 2.
Two way fluid structure interaction hydroelastic simulation of vibrating membranes with applications in marine engineering using ANSYS fluent FSI
Year: 2020

Modern ocean engineering is developing quickly and floating cities, new energy harvesting methods and novel marine systemsare unfolding in the 21stcentury. The intelligent design of many such systems is exploiting "compliant" structures which deform under fluid dynamic loading, yet retain their function and integrity. These include folating solar membrane panels, breakwaters, OTEC systems and marine robotic inspection devices e.g. Mantadroid and MIT's Soft robotic fish. The nature of the ocean is unpredicatble and such systems must be designed for a range of loading conditions. Conventional rigid designs are now being superseded by compliant, flexible systems largely due to the development of novel materials. These structures interact with the hydrodynamic environment and perform "hydroelastically" This involves two way fluid structure interaction (FSI) between the fluid and the deforming structure and requires advanced analysis methods. The process is generally nonlinear and commercial computational fluid dynamics/finite element codes are presently the most robust method for conducting such simulations. Indeed other loads may also arise including ice, tidal, earthquake, debirs impact etc. All these loadings can be accomodated reasainably with FSI analysis. In the present work, motivated by examining in greater detail the mechanics of deformable membranes (for submerged ocean energy systems) a detailed analysisof the FSI behaviour of a vertical membrane structure is conducted. The analysis is performed ona thin plate acting as a membrane, experiencing under damped oscillatory motion within a still marine environment (wave effects are ignored) Linear elastic material behaviour is considered and extensive visualization of pressure, velocity and Von Mises (equivalent) stress contours are provided. Mesh independence is conducted and validation of the tip deflection with COMSOL multiphysics software is included. Extensive interpretation of the results is included and future modification pathways for more complex analysis are outlinedincluding wave effects with different order theories.
Body Mass Index and Decline in Cognitive Function in Older Black and White Persons
Venue: The journals of gerontology. Series A, Biological sciences and medical sciences
Year: 2018

While body mass index (BMI) is higher in black compared to white persons, little is known about BMI and change in cognition in cohorts with a large proportion of blacks. We examine relations of BMI with decline in global cognition and five cognitive domains, in older blacks and whites, and determine whether relations differ by race.  Participants were 2,134 persons without baseline dementia (33% black; 75% women; mean age =77.9 [range 53 100] and education 14.7 years, Mini Mental State Examination 28.0) enrolled in one of two longitudinal, community based cohort studies of aging (Minority Aging Research Study; Rush Memory and Aging Project) Summary scores of global cognition and five domains were based on 19 neuropsychological tests administered annually. Mixed effects models, controlling for age, sex, education, and race, were used to examine the relation of baseline BMI to change in cognition.  Baseline BMI 28.4 units (30.3 in blacks [95% confidence interval (CI) 27.2 27.7] 27.4 in whites [95% CI: 29.8 30.7] During a mean annual follow up of 6 years (SD 4) lower baseline BMI was related to faster decline in global cognition (p .002) and semantic memory (p .001) and episodic memory (p .004) but not working memory, perceptual speed, or visuospatial ability (all p .08) The relationship of BMI with change in cognition was not modified by race (all p .09)  Late life lower BMI relates to faster rates of decline in cognition, specifically semantic memory and episodic memory, in both blacks and whites. The effect of BMI on cognition appears to be similar in both racial groups.
Cross Technology Communication through Symbol Level Energy Modulation for Commercial Wireless Networks
Venue: 2020 IEEE International Conference on Pervasive Computing and Communications (PerCom)
Year: 2020

The coexistence of heterogeneous devices in wireless networks brings a new topic on cross technology communication (CTC) to improve the coexistence efficiency and boost collaboration among these devices. Current advances on CTC mainly fall into two categories, physical layer CTC and packet level energy modulation (PLEM) The physical layer CTC achieves a high CTC data rate, but with channel incompatible to commercial devices, making it hard to be deployed in current wireless networks. PLEM is channel and physical layer compatible, but with two main drawbacks of the low CTC data rate and MAC incompatibility, which will induce severe interference to the other devices' normal data transmissions. In this paper, we propose symbol level energy modulation (SLEM) the first CTC method that is fully compatible with current devices in both channel and the physical/MAC layer processes, having the ability to be deployed in commercial wireless networks smoothly. SLEM attaches the CTC bits to one WiFi data packet through adjusting the energy levels of WiFi symbols, achieving concurrent CTC and WiFi transmissions. We make theoretical analysis to figure out the performance tradeoff between CTC and WiFi, and also conduct experiments to demonstrate the feasibility of SLEM and its performance under different network situations.
Generalized Weierstrass semigroups and their Poincare series
Venue: Finite Fields Their Appl.
Year: 2019

We investigate the structure of the generalized Weierstrass semigroups at several points on a curve defined over a finite field. We present a description of these semigroups that enables us to deduce properties concerned with the arithmetical structure of divisors supported on the specified points and their corresponding Riemann Roch spaces. This characterization allows us to show that the Poincare series associated with generalized Weierstrass semigroups carry essential information to describe entirely their respective semigroups.
A New Conic Approach to Semisupervised Support Vector Machines
Year: 2016

We propose a completely positive programming reformulation of the 2 norm soft margin model. Then, we construct a sequence of computable cones of nonnegative quadratic forms over a union of second order cones to approximate the underlying completely positive cone. An optimal solution can be found in finite iterations using semidefinite programming techniques by our method. Moreover, in order to obtain a good lower bound efficiently, an adaptive scheme is adopted in our approximation algorithm. The numerical results show that the proposed algorithm can achieve more accurate classifications than other well known conic relaxations of semisupervised support vector machine models in the literature.
Problem Gambling and Family Violence in Chinese Help Seeking Clients: Prevalence, Impact and Coping
Year: 2012

Despite substantial evidence that problem gambling is associated with a wide range of family difficulties, only limited effort has been devoted to studying family coping styles and impacts of problem gambling on families, including family violence. In particular, scientific studies on the above issues amongst Chinese communities are non existent. The aims of this study were to a) determine the prevalence of family and couple violence among families who experience gambling problems; b) explore how family members cope with their family members' gambling problems and c) examine the relationships between family coping styles and family impacts. A total of 285 participants (182 gamblers and 103 family members) were recruited from Tung Wah Group of Hospitals Even Centre over a 12 month period. Information on demographic characteristics, gambling behaviour, alcohol and drugs use, gambling related family impacts and coping, family violence victimization and perpetration, and psychological symptoms was collected. Results showed that 11.6% (n=12) of family members reported having experiences of being a victim in family and couple violence, and 12.6% (n=13) of them reported being the perpetrator. Furthermore, 14.6% (n=15) reported being both the victim and perpetrator. For the gambler's group, 24.2% (n=44) reported being victimized, 6.0% (n=11) reported being the perpetrators, and 4.9% (n=9) reported being both the victim and perpetrator. Significant differences on coping styles and family impacts between problem gamblers and family members of gamblers were found. Impacts on family had stronger correlations with withdrawal coping than tolerant inactive and engaged coping. As the current service provision is fragmented with little attention paid to family impacts and coping, the findings of this research will be useful for the development of an appropriate intervention and treatment model including family coping skill training programs and the inclusion of family and couple therapy in treatment programs.
The roots of division, activism, and civil society in Nigeria
Year: 2018

Throughout its more than a century history, Nigeria has had a checkered story of ethnicity, divisions, violence, and mutual suspicions. Nigeria's experience with colonialism engendered a Western oriented activism and metamorphosis of civil society, which have affected governance in diverse ways. Existing civil society is nonetheless affected by contextual factors such as patronage, corruption, and ethnicism, with internal democratization of civil society groups a major factor that could advance their contribution to governance and local development. Nigeria, however, remains at a crossroads, due to deep seated ethnic animosity as well as the failure of contemporary activism and civil society to redeem the nation from schismatic ills rooted in its colonial foundations.
The Effect of Artificial Intelligence on the Sales Graph in Indian Market
Year: 2020

Artificial Intelligence (AI) has been the biggest revolution of the 21st century impacting every aspect of the business, sales being no different. The paper experiments the effect of marketing on 4500 customers using AI and humans. The outcomes of the research reveal the effectiveness of AI is the same as experienced salesmen and 2.7 times better than inexperienced salesmen is closing the sales calls. The sales graph experienced a dip by over 86.23% when it was revealed to the customer that the interface is with the machine, not humans and reduced the duration of the call substantially. The paper shows that Indians do not believe Artificial Intelligence and still prefer human interface as they do not trust machines over human emotions. The effectiveness of AI drastically reduces despite its superiority over humans in various aspects. The paper identifies the strategies to overcome the trust deficit that exists among Indian customers. The outcomes show how AI can be used, and how marketing could be done using AI in conservative markets such as India.
Learning a deep network with spherical part model for 3D hand pose estimation
Venue: 2017 IEEE International Conference on Robotics and Automation (ICRA)
Year: 2017

3D hand pose estimation is a hot research topic in recent years. It's been widely used in many advanced applications for virtual reality and human computer interaction, since it provides a natural interface for communication between human and cyberspace. Despite the fast development of this field, it is still a difficult task due to the various challenges. In this paper, we aim to build a 3D hand pose estimation system which can correctly detect human hands and accurately estimate its pose using depth images. To guarantee the robustness of our system, we design a hand model called spherical part model (SPM) and train a deep convolutional neural network using this model. Moreover, to reduce the influence of human's omissions, we use a data driven approach to integrate them together. Our network can more accurately estimate hand pose based on prior knowledge of human hand. To demonstrate the superiority of our method, a complete experiment is conducted on two public and one self built datasets. The results show that our system can detect human hands with average precision at almost 90% and the average error distance of the pose estimation is about 10 millimeters, and is better than the other state of the art works.

Venue: The Journal of chemical physics
Year: 2019

The fast increase in available computation power allowed us to decrease the cooling rate in molecular dynamics (MD) simulation of vitrification by several orders of magnitude. While the reliability of the MD simulation should obviously benefit from this increase in the computational power, in some cases, it led to unexpected results. In particular, Ryltsev et al.

Limites a la autonomia de la voluntad privada en la celebracion de los contratos de condiciones uniformes suscritos por los usuarios del servicio publico ordinario de aseo en las empresas EMAF E.S.P. y la Piedecuestana E.S.P.
Year: 2019

La autonomia de la voluntad es una expresion de la libertad individual. Se encuentra protegida por diferentes normas de orden nacional, sin embargo, en otros escenarios, es necesaria la intervencion del Estado para poder limitar esta autonomia, con esto no se busca imponer cargas o excluir derechos de personas, sino todo lo contrario, limita dicha voluntad para la proteccion de estas personas. En la proteccion al usuario, la autonomia de la voluntad es casi inexistente, ya que los usuarios y/o suscriptores no pueden negociar ninguna clausula contractual. Esta limitacion se da, por la falta de importancia a la hora de contratar, por normas de defensa al consumidor, entre otras. De igual manera el contrato de condiciones uniformes, es un contrato manejado por disposiciones legales de derecho civil; su naturaleza juridica se sustenta en una serie de elementos que lo caracterizan como instrumento regulatorio en la prestacion del servicio publico domiciliario (ley 142 de 1994) de manera uniforme y consensual, para todos los usuarios indeterminados, que se adhieran a el de forma libre y tambien voluntaria. El proposito de mi presente investigacion, es elaborar una revision profunda de los conceptos, caracteristicas y naturaleza que tiene el contrato de servicios publicos domiciliarios, a fin de poder establecer el alcance juridico de este instrumento para la proyeccion social de las personas.
Storage Structure of Student Record based on Hyperledger Fabric Blockchain
Venue: 2019 International Conference on Advanced Information Technologies (ICAIT)
Year: 2019

Student records (SR) are needed to be regularly protected for safe access and security control. The blockchain system can support security, confidentiality, unchangeable, transparency and access control service. Although Hyperledger Fabric blockchain is a scalability modular architecture, various configuration elements affect the performance of transaction access time. Moreover, it cannot provide an efficient indexing capability on the transaction. In this paper, a storage structure that provides better access time is presented. Firstly, the suitable block size is proposed for transactions based on the configuring parameter and the transaction arrival rate to reduce the latency of transaction storage time. Secondly, the metadata of the SR block is replicated on an off chain database to overcome the limitation of indexing capability and performance issue. SR data will be accessed transparently with greater performance and lower the costs of manpower and time.
Presenting modified Servqual model to evaluate flight attendant services: Iran Air case study
Venue: Journal of Airline and Airport Management
Year: 2019

The investigation of the customer`s viewpoints and utilizing their ideas and expectations in improving the quality of the products, has turned out to be one of the key concerns of the companies working in all fields. Airline industry as one of the most extensive modes of transportation should be strictly accurate in providing services to their customers. This article attempts to investigate important dimensions from passengers' point of view and present a model which would evaluate the flight attendant's performance. In order to achieve this purpose, on the basis of the literature and experts' and passengers' point of view, the SERVQUAL model has been modified with 26 factors in 6 dimensions. Then 300 data have been gathered for the Factor Analysis Model. As a result, a model with high goodness of fit has been developed which could be used as a tool of measuring quality of service with a high degree of certainty. In the end, running the model in Iran air, most differences were as below: 1 Improvement 2 Responsiveness 3 Empathy 4 Assurance 5 Tangibles 6 Reliability. In general, in this model, all services with which employees are involved are observed. However, the main issue in this research is related to attendant team. Consequently, considering that many of these indicators have different meanings in assessing customer satisfaction in relation to the performance of flight attendant; modifications should be made to the dimensions of the SERVQUAL model.
