Design And Implementation Of A Voice-Controlled Prosthetic Hand, Musa Hakan Asyali, Mustafa Yilmaz, Mahmut Tokmakçi, Kanber Sedef, Beki̇r Hakan Aksebzeci̇, Rohin Mittal

Turkish Journal of Electrical Engineering and Computer Sciences

Current hand prostheses are mostly driven by electromyography (EMG) signal, and existing experiments have proved that multichannel EMG signal controls are not suitable due to early fatigue problems and high effort requirements to perform even simple activities. Therefore, in this study we present a new voice-controlled active hand prosthesis to perform several basic tasks. We first designed a novel multifingered prosthetic hand with the ability of picking up and releasing objects. The prosthetic hand employs 3 DC motors and gears to transfer motion to the linked iparts of the fingers. We used flexible thin-film resistive force sensors at the fingertips …

Papr Reduction Using Artificial Bee Colony Algorithm In Ofdm Systems, Necmi̇ Taşpinar, Dervi̇ş Karaboğa, Mahmut Yildirim, Bahri̇ye Akay

Turkish Journal of Electrical Engineering and Computer Sciences

Partial transmit sequence (PTS) is an attractive scheme for peak-to-average power ratio (PAPR) reduction in orthogonal frequency division multiplexing (OFDM) systems, but its high computational complexity to find optimum phase factors is the main drawback. In this paper, we propose PTS based on an artificial bee colony (ABC) algorithm (ABC-PTS) for reducing the computational complexity of the PTS in the OFDM system. The ABC-PTS was compared to conventional PTS using a random search strategy (RS-PTS) and optimum PTS. In addition, the bit error rate (BER) performance of the ABC-PTS was shown when a high power amplifier (HPA) was used for …

Stray Magnetic Field Distributed Around A Pmsm, Ali̇ Ahmed Adam, Kayhan Gülez, Seli̇m Köroğlu

Turkish Journal of Electrical Engineering and Computer Sciences

In this work, the low frequency electromagnetic emission from permanent magnet synchronous motors is studied. The main objective is to provide a safety region for humans in the vicinity of these motors, especially as these motors are now being used widely in inhabited areas, where high flux densities are expected. In this study, a new proposed equivalent magnetic circuit is used to estimate the stray fields at the surface of the motor. The analysis showed that the emission of the stray field in the radial direction depends on the permeability of the stator body. Low values of permeability may result …

New Srco With Explicit Current-Mode Output Using Two Ccs And Grounded Capacitors, D R. Bhaskar, Kasim K. Abdalla, Raj Senani

Turkish Journal of Electrical Engineering and Computer Sciences

A new Grounded-Capacitor Single Resistance Controlled Sinusoidal Oscillator (SRCO) with explicit current output using two Current Conveyors (CCs) and five passive elements is presented. The proposed circuit offers (i) independent control of condition of oscillation and frequency of oscillation, (ii) low active and passive sensitivities, (iii) use of both the grounded capacitors (suitable for IC implementation) and (iv) reasonably good frequency stability. The workability of the proposed configuration has been confirmed by the PSPICE simulations.

Imitation Of Basic Hand Preshapes By Fluid Based Method: Fluidics Formation Control, Umut Ti̇lki̇, İsmet Erkmen, Aydan Müşerref Erkmen

Turkish Journal of Electrical Engineering and Computer Sciences

In this paper, a new approach is developed, avoiding the correspondence problem caused by the difference in embodiment between imitator and demonstrator in imitation learning. In our work, the imitator is a fluidic system of dynamics totally different than the imitatee, which is a human performing hand gestures. The fluidic system is composed of fluid particles, which are used for the discretization of the problem domain. In this work, we demonstrate the fluidics formation control so as to imitate by observation basic hand preshaping features. Our fluidic formation control is based on setting suitable parameters of Smoothed Particle Hydrodynamics (SPH), …

Four Quadrant Fgmos Analog Multiplier, Si̇nem Keleş, Hulusi̇ Hakan Kuntman

Turkish Journal of Electrical Engineering and Computer Sciences

A novel four-quadrant analog multiplier using floating gate MOS (FGMOS) transistors operating in the saturation region is presented. The drain current is proportional to the square of the weighted sum of the input signals. This square law characteristic of the FGMOS transistor is used to implement the quarter square identity by utilizing only six FGMOS transistors. The main features of this remarkably simple multiplier circuit configuration are the large input signal range equal to 100% of the supply voltage, nonlinearity of 0.0081%, bandwidth of 1.4--1.5 Ghz and THD of maximum 2.67% (while the inputs are at their maximum values).

Recent Advances In The Synthetic And Mechanistic Aspects Of The Ruthenium-Catalyzed Carbon-Heteroatom Bond Forming Reactions Of Alkenes And Alkynes, Chae S. Yi

Chemistry Faculty Research and Publications

The group’s recent advances in catalytic carbon-to-heteroatom bond forming reactions of alkenes and alkynes are described. For the C–O bond formation reaction, a well-defined bifunctional ruthenium-amido catalyst has been successfully employed for the conjugate addition of alcohols to acrylic compounds. The ruthenium-hydride complex (PCy₃)₂(CO)RuHCl was found to be a highly effective catalyst for the regioselective alkyne-to-carboxylic acid coupling reaction in yielding synthetically useful enol ester products. Cationic ruthenium-hydride catalyst generated in-situ from (PCy₃)₂(CO)RuHCl/HBF₄·OEt₂ was successfully utilized for both the hydroamination and related C–N bond forming reactions of alkenes. For …

Surface Characteristics Of Silica Polyamine Composites, Jesse James Allen

Graduate Student Theses, Dissertations, & Professional Papers

The goals of this dissertation were to explore the surface characteristics of silica polyamine composites (SPC) by elucidating coordination environments, measuring surface stability, and comparisons with analogous materials. Application of SPC materials as supports for heterogeneous catalysts was also investigated. Analytical techniques including NMR (both solution state and solid state), mercury porosimetry, and scanning electron microscopy (SEM) were used to characterize the materials.

Cobalt was found to irreversibly bind to the chelating polymer polyethyleneimine (PEI). This was due to oxidation of Co2+ to Co3+, which was enabled by the chelate's ligand field stabilization. Detailed analysis of SPC surface coordination environments …

The Categories Of Graphs, Demitri Joel Plessas

Graduate Student Theses, Dissertations, & Professional Papers

In traditional studies of graph theory, the graphs allow only one edge to be incident to any two vertices, not necessarily distinct, and the graph morphisms must map edges to edges and vertices to vertices while preserving incidence. We refer to these restricted morphisms as strict morphisms. We relax the conditions on the graphs by allowing any number of edges to be incident to any two vertices, as well as relaxing the condition on graph morphisms by allowing edges to be mapped to vertices, provided that incidence is still preserved. We call the broader category of these graphs and …

The Economic Impacts Of Wolves On Calf Production On Western Montana Cattle Ranches Beyond Direct Depredation, Joseph Ramler

Graduate Student Theses, Dissertations, & Professional Papers

A novel sample of 18 western Montana cow-calf ranching operations were analyzed over a 16 year time period (1995-2010) using an ordinary least squares linear regression estimation model with robust standard errors focused on the potential effects wolves may have on average calf weight gain. Incorporating calf sex, calf breed, ranch, and year fixed effects into the estimation model, a vector of variables that changed both across ranches and over time were used to significantly explain (F = 59.32; p < 0.001) the variation in yearly average calf weaning weights on sample ranches with fairly good accuracy (R2 = 0.846). The use of hormone implanting (â=24.5), calf age (â=.34), annual aggregate precipitation (â=2.16), annual aggregate snowfall (â=-0.24), annual average temperature (â=4.27), and the standard deviation of NDVI (â=1.67) were found to be significant at least at the .1 level. One measure used to account for wolf presence on sample ranches based on yearly estimated wolf home range data from Montana Fish, Wildlife & Parks was found to have an insignificant effect on average calf weight (p = .569). The other measure used to account for wolf presence on sample ranches was found to be a significant factor on calf weight gain. On average, sample ranches that experienced at least one Wildlife Service (WS) confirmed wolf depredation on the ranch, weaned calves that were approximately 20 pounds lighter than ranches that did not have a WS confirmed wolf depredation in the same year, holding all else constant. The results suggest that calves on western Montana ranches that experience at least one WS wolf depredation in a year gain 20 pounds less weight than if there hadn’t been a WS confirmed wolf kill which directly correlates to decreased economic revenue received by affected ranchers.

The Effects Of Large Herbivores On Small Mammal Communities, Plants And Ecosystem Processes In Northern Arizona, Elliott Wentworth Reed Parsons

Graduate Student Theses, Dissertations, & Professional Papers

Large herbivores are major drivers of community structure and function in many terrestrial systems. Through their direct effects on plants, large herbivores can influence the structure and complexity of habitats, the population abundance of animals that rely on those habitats, and the rates of ecosystem processes within those systems. These manifold impacts on systems are potentially magnifying, as removal of top predators and changes in land use have triggered large increases in large herbivore populations. Although increasing evidence suggests that large herbivores can critically shape the structure and function of the ecosystems they inhabit, few studies have detailed the direct …

The Financial Crisis Of 2008-09: Capitalism Didn't Fail, But The Metaphors Got A 'C', Jeffrey M. Lipshaw

Suffolk University Law School Faculty Works

This is a paper for the Minnesota Law Review's October 15, 2010 symposium, "Government Ethics and Bailouts: Past, Present, and Future." The panel topic is "The Past: Did Capitalism Fail?" The paper addresses not the merits and demerits of modern global financial systems, but instead how those of us who are not financial professionals might make sense of them, particularly when they are in catastrophic mode. The thesis is that the question itself reveals the extent to which the financial crisis has not been so much about whether an economic system succeeds or fails, but the meaning human beings draw …

Explanations regarding the link between physical activity and cognitive health were provided in 57.7% of articles. These explanations were generally consistent with empirical evidence; however, few articles included empirical evidence. Physical activity recommendations were presented in 80.8% of articles; a wide range was recommended (90–300 min of …

Fitness And Adiposity As Predictors Of Functional Limitation In Adults, Andréa L. Maslow, Anna E. Price, Xuemei Sui, Duck-Chul Lee, Ikka Vuori, Steven N. Blair

All PTHMS Faculty Publications

This study examined the associations of body mass index (BMI), waist circumference (WC), and cardiorespiratory fitness (CRF) with incident functional limitation (IFL) in adults. Patients (n = 2400), 30+ years [mean age, 45.2 (SD, 8.3); 12% women], completed a baseline health examination during 1979 to 1995. CRF was quantified by age-and sex-specific thirds for maximal treadmill exercise test duration. Adiposity was assessed by BMI and WC (grouped for analysis according to clinical guidelines). Incident IFL was identified from mail-back surveys during 1995, 1999, and 2004. After adjusting for potential confounders and either BMI or WC, CRF was inversely related to …

Getting To Know You: Key Clinical Concepts In Relationship-Based Interventions And Neurobehavioral Observations With Young Infants, Yvette Blanchard

All PTHMS Faculty Publications

The newborn infant is a social organism, pre-disposed to interact with his caregiver and able to elicit the kind of caregiving necessary for successful adaptation. The earliest developmental task of the newborn is to organize behavior to be able to play an active role in influencing the caregiving environment and eliciting the kind of support needed for development. This task is accomplished through the attainment of self-regulation or balanced neurobehavioral functioning of the infant's autonomic, motor, state, and responsivity behavioral dimensions as described by Als.

Profile Of The Role Of Professional Nursing In Anti-Bullying In The Community: A Systems And Policy Approach, Harriet Fields, Susan Schwartzman

The Bce Blunder: An Argument In Favour Of Shareholder Wealth Maximization In The Change Of Control Context, Patrick Lupa

Dalhousie Journal of Legal Studies

The job of a corporate director has become increasingly complex - gone are the days where board members were essentially “rubber stamps” to management initiatives. Currently, the board of directors is the highest governing authority within the management structure of any company. Some responsibilities of boards include selecting, evaluating, and approving compensation for the company’s chief executive officer, approving the company’s financial statements and paying dividends. One of the most difficult decisions that a director may face has to do with recommendations on change of control transactions. Changes of control include transactions where shareholders lose control of the corporation or …

Taking The Risk Out Of Termination: An Enterprise Risk Management Analysis Of The Normative System Of Employment Standards Challenged By Honda V Keays, Ryan Henry Edmonds

Dalhousie Journal of Legal Studies

Over many years, Canadian courts have crafted a unique body of employment law jurisprudence. The purpose of this paper is to discuss how that jurisprudence was unraveled when the Supreme Court of Canada rendered its decision in Honda v. Keays. That holding, in effect, overturned aspects of Wallace v. United Grain Growers; a case that transformed how non-unionized employees were thought of and treated in Canadian society. This paper examines the analytical underpinnings of wrongful dismissal law’s previous regime on bad faith damages and juxtaposes it to the new regime in Keays, concluding that the shift in focus from employer …

Six Degrees Of Separation: Canadian Accessory Liability In Afghan War Crimes, Deborah Bayley

Dalhousie Journal of Legal Studies

As confident as Byers, Schabas and many others are in their assertion that Canada has committed war crimes, the matter is unfortunately far more complex and far less certain. One of the primary reasons for this complexity is that Canada is not the party that allegedly committed torture. It is widely agreed that the acts of torture were undertaken solely by Afghan authorities, making them the perpetrators in this case. If the allegations against Canada turn out to be founded, Canada’s participation could at best be characterised as accessory. This brings the matter into an exceptionally murky area of law …

Does The Charter Follow The Flag? Revisiting Constitutional Extraterritoriality After R V Hape, Chanakya Sethi

Dalhousie Journal of Legal Studies

Jacques Maritain, the noted philosopher and political thinker and a principal drafter of the Universal Declaration of Human Rights, once contended that “political philosophy must get rid of the word, as well as the concept, of Sovereignty.” He reasoned as much “not because [sovereignty] is an antiquated concept,” or “because the concept of Sovereignty creates insuperable difficulties and theoretical entanglements in the field of international law,” but because “this concept is intrinsically wrong and bound to mislead us if we keep on using it.” Maritain’s proposal may have been exceedingly bold and his criticisms perhaps too harsh, but they nonetheless …

Risk V Benefits: The Use Of Selective Serotonin Reuptake Inhibitors In Children, Kim Wilton

Dalhousie Journal of Legal Studies

Selective Serotonin Reuptake Inhibitors (SSRIs) are a class of antidepressant medications that came on the market in the late eighties and early nineties. SSRIs were found to be clinically effective in treating clinical depression, and anxiety disorders in adults and had less cumbersome side effects compared to the older Tricyclic antidepressants. The first drug in this class introduced was fluoxetine (Prozac), which was soon followed by paroxetine (Paxil), sertraline (Zoloft), citalopram (Celexa), fluvoxamine (Luvox), and escitalopram (Lexapro). Today the uses of SSRIs have broadened to include treatment for “Post-Traumatic Stress Disorder, pre-menstrual dysphoric disorder, urinary incontinence” and many other seemingly …

The Patentability Of Human Embryonic Stem Cells: Is The Inconsistent Application Of The European Union Biotechnology Directive's Moral Exclusion Clause Undermining Investor Confidence In Europe, Providing A Competitive Advantage To The United States?, Stephen R. Donnelly

Dalhousie Journal of Legal Studies

The original justification for Directive 98/44/EC of the European Parliament and of the Council of 6 July 1998 on the Legal Protection of Biotechnological Inventions (the Directive) was to promote the growth of the European life science sector by harmonizing and clarifying European biotechnology patent laws. As early as 1985, the European Commission had identified the fragmentation of European patent laws as a potential problem. The Directive thus aimed to address obstacles to the unity of the internal market, which would arise if national Member States adopted divergent and uncoordinated policies and legislation in a field of economic activity that …

Turning Citizens Into Subjects: Why The Health Insurance Mandate Is Unconstitutional, Randy E. Barnett

Georgetown Law Faculty Publications and Other Works

In 2010 something happened in this country that has never happened before: Congress required that every person enter into a contractual relationship with a private company. While the author realizes that writers make lots of factual claims that readers are wise to be skeptical about, he proves that an economic mandate like this one is unprecedented. If this mandate had ever happened before, everyone reading this passage would know all the contracts the federal government requires them to make, upon pain of a penalty enforced by the Internal Revenue Service (IRS). No reader, however, can recite any such mandate and …

Legislative Organization And Administrative Redundancy, Michael Doran

Georgetown Law Faculty Publications and Other Works

Congress regularly enacts legislation providing for redundant administrative programs. For example, there are more than 100 federal programs for surface transportation, 82 programs to ensure teacher quality, 80 programs to promote domestic economic development, and 47 programs to provide employment and job-training services. Recent high-profile legislation–-such as the financial-industry reform measure and the health-care reform measure–-add new programs without repealing existing ones directed at the same policy goals. Prior academic analyses generally have not considered why Congress pursues redundancy. This article addresses that question through both theoretical and institutional analysis.

The article first constructs an organizational theory that attributes redundancy …
