Semiconductor Nanowires: Epitaxy and Applications

Semiconductor nanowires are nanoscale objects formed by bottom-up synthesis. In recent years their unique properties have been exploited in fields such as electronics, photonics, sensors and the life sciences. In this work, the epitaxial growth of nanowires and their applications were studied. Heteroepitaxial growth of III-V nanowires on silicon substrates was demonstrated. This may enable direct band gap materials for optoelectronic devices, as well as high-mobility, low-contact resistance materials for electronics, to be integrated directly on the Si platform. Furthermore, gold-free nanowire synthesis on Si was demonstrated, which offers an advantage in terms of compatibility with established Si processing. Controlled nanowire synthesis by employing lithography was demonstrated. This combination of established "top-down" planar processing, and "bottom-up" nanowire growth, enables deterministic synthesis with individual nanowire site control. The process was first demonstrated with electron beam lithography and later extended to nanoimprint lithography, which is a parallel, high-throughput method, suitable for commercial volumes. Nanowire applications were demonstrated by three examples: (i) Vertical light-emitting diodes (LEDs) based on GaAs/InGaP core/shell nanowires, epitaxially grown on GaP and Si substrates. LED functionality was established on both kinds of substrates. This provided a direct demonstration of light-emitting devices on Si made possible by heteroepitaxial III-V nanowire growth on Si. (ii) A single-electron transistor constructed from a heterostructured nanowire with an InAs island sandwiched between two InP barriers. The narrow diameter of the nanowire provides the lateral confinement, and the tunnel barrier resistances are tunable by varying the InP barrier thickness. Coulomb oscillations and Coulomb blockade with a charging energy of approx. 4 meV were observed. (iii) Sensory nerve cell interactions with nanowires. Substrates covered with 2.5 um long and 50 nm diameter nanowires supported cell adhesion and axonal outgrowth. The cells interacted closely with the nanostructures, and viable cells penetrated by wires were observed, as well as wire bending due to forces exerted by the cells. (Less)
Factors Associated With Ruminative Thinking in Individuals With Gender Dysphoria

This study aimed to examine psychosocial factors and medical history as well as symptoms of depression, anxiety, and stress associated with ruminative thinking in transgender people with gender dysphoria (GD) before undergoing gender affirmation surgery (GAS). This study evaluated 189 participants with GD (111 trans women and 78 trans men) from a specialized service for GAS in southern Brazil. Semi-structured interviews were conducted, and participants were asked to complete self-report questionnaires. We recovered participants' sociodemographic and psychosocial data (e.g., history of sexual abuse, expulsion from home, and history of drug use) and data regarding their clinical history (e.g., medication, history of suicidal ideation and attempted suicide, and HIV status). Further, we implemented the Depression, Anxiety and Stress Scale (DASS-21) to examine participants' psychological state, as well as the Ruminative Response Scale (RRS) to assess ruminative thinking, which includes brooding and reflection. The predictor variables were those that exhibited a minimum level of significance of p ≤ 0.05 in multivariate linear regression. The ruminative thinking scores for trans women were higher than those of trans men (Brooding p = 0.014; Reflection p = 0.052). In the multivariate model, suicidal ideation, moderate depression, and severe/very severe anxiety were associated with both brooding and reflection. Feminine gender identity and stress symptoms moderated only brooding, while anxiety symptoms moderated only reflection. Our findings show that trans women had the highest ruminative thinking scores, and that depression, anxiety, stress, and suicidal ideation were associated with ruminative thinking in total sample. Psychological symptoms should be examined in the context of gender affirmation surgery to minimize the possibility of adverse mental health outcomes. Follow-up studies are required to measure ruminative thinking levels more accurately and to identify its predictors.

High frequency dividing synchronous oscillator using modified emitter couple logic inverters

A synchronous oscillator using a high speed low-voltage emitter coupled logic (ECL) inverter has been reported. Using the positive feedback the locking range increases, compared to the oscillator without any positive feedback. A maximum improvement (increase) of percentage locking range of around 105% was obtained from circuit simulation as well as from practical circuit, using discrete components. Because the locking range is maximum at double the output frequency of the oscillator, this oscillator can be used as a high frequency divider circuit. The circuit requires a supply voltage of 2.1 V.

Blood flow modeling for patient-specific bypass surgery in lower-limb arteries

Every day in Belgium, at least one or two people will undergo a bypass surgery in the lower-limb arteries. This medical procedure consists of replacing an occluded section of the leg arteries with an artificial vessel, in order to allow blood to flow downwards of this blockage. Even though this intervention is very common, failure of this treatment within five years reaches up to 60%. In order to improve our understanding of the causes of bypass failure, one approach is to study the local hemodynamics (i.e. the blood flow circulation) in these vessels, as this factor strongly influences the initiation and progression of arterial diseases. This thesis addresses this objective by modeling the patient-specific arterial hemodynamics. As each patient is characterized by his own physiology (e.g. morphology, severity of the disease) and is treated by a bypass graft of fixed characteristics (e.g. material, length, location of the anastomoses), each clinical case needs to be considered individually. In the first part of our work, blood pressure, velocity and flow rate in the network of arteries are modeled with a one-dimensional model of the arteries and lumped windkessel models of the secondary and distal vessels. The 18 parameters of this coupled model are then computed in order to reflect the pathological condition of the patient. Thanks to the set-up of an experimental protocol of data acquisition, in-vivo measurements of hemodynamics have been acquired on 25 patients operated with bypass surgery. The comparison of these in-vivo signals with simulations from the numerical model enabled us to improve and to validate our patient-specific numerical model. In the second part of this thesis, the dynamic of blood is considered as impulses of waves which are generated by the contractions of the heart, and which propagate throughout the arterial network. By using the wave intensity analysis method, we analyzed and characterized these waves in the pathological arteries of the leg, and emphasized the effects of the bypass.
Software Configuration Management in Agile Development

Software Configuration Management (SCM) is an essential part of any software project and its importance is even greater on Agile projects because of the frequency of changes. In this chapter, we argue that SCM needs to be done differently and also cover more aspects on Agile projects. We also explain how SCM processes and tools contribute both directly and indirectly to quality assurance. We give a brief introduction to central SCM principles and define a number of typical Agile activities. Subsequently, we show that there are general SCM guidelines for how to support and strengthen these typical Agile activities. Furthermore, we establish a set of requirements that an Agile method must satisfy to benefit the most from SCM. Following our general guidelines, an Agile project can adapt the SCM processes and tools to its specific Agile method and its particular context. (Less)

Energy and exergy analysis of data center economizer systems

ENERGY AND EXERGY ANALYSIS OF DATA CENTER ECONOMIZER SYSTEMS By Michael E. Meakins Electrical consumption for data centers is on the rise as more and more of them are being built. Data center owners and operators are looking for methods to reduce energy consumption and electrical costs. One method of reducing facility costs for a chilled water plant is by adding an economizer. Most studies concerning economizer systems are conducted largely by looking at energy alone since the primary focus is reducing electrical costs. Understanding how much exergy is destroyed, where it is destroyed, and why it is destroyed provides a more complete view on how environmental impacts can be minimized while reducing energy usage. The purpose of this study is to develop energy and exergy-based models of the most common economizer systems. A normal chiller plant without an economizer and a chiller plant with an indirect wet-side economizer (the most common type of economizer system) are compared. Results show outdoor conditions influence facility energy consumption and exergy destruction. For a chiller plant operating with an economizer, the CRAH is found to be the largest source for exergy destruction. For a chiller plant without an economizer, the chiller is the largest source for exergy destruction.

MORPHOMETRIC CHARACTERIZATION OF LOCAL AND EXOTIC CHICKEN GENOTYPES IN THREE AGRO-ECOLOGIES OF NORTHERN ETHIOPIA

The northern part of Ethiopia is endowed with local and exotic breeds of chicken; however, their morphometric characterization needs to be done to support future improvements and conservation. Hence, the study was conducted in three agro-ecologies (lowland, midland, and highland) of Northern Ethiopia to assess the morphometric traits of local and exotic (Naked-neck) chicken genotypes. The experiment was designed as 4x2 factorial with Chicken genotype (4 levels: local from each of lowland, midland and highland, and exotic from lowland) and Sex (2 levels: female and male) being the factors. ANOVA was conducted to determine the main and interaction effects of these factors on 21 morphometric traits. The results revealed significant interaction of Chicken genotype and Sex on all morphometric traits other than skull length, skull width, skull index and neck length highlighting the presence of vast sex specific differences among the genotypes. Apart from comb, earlobe and beak indices and wattle width, male Naked-neck (from lowland) have significantly higher values than the other seven combinations. The morphometric variations of chicken genotypes unveiled in this study are good indicators of genetic diversity of chicken population in Northern Ethiopia and calls for designing community based genetic improvement program to maximize desirable traits.
A decision support system for optimising the order fulfilment process

Many authors have highlighted gaps at the interfaces between supply chains (SCs) and demand chains. Generally, the latter tends primarily to be ‘agile’ by maximising effectiveness and responsiveness while the former tends to be ‘lean’ by maximising efficiency. When, in the SC, disruptions (that lead to stock-out situations) occur after customer orders have been accepted, managers are faced with the problem of maximising customer satisfaction while taking into consideration the conflicting objectives of the supply and demand sides of the order fulfilment process. This article proposes a cross-functional multi-criteria decision-making (advanced available-to-promise) tool that provides different strategic options from which a solution can be chosen. It also proposes a performance measurement system to support the decision-making and improvement process. The results of some experimental tests show that the model enables to make strategic decisions on the degree of flexibility required to achieve the desired level of customer service.
PROTOTYPING A NEGOTIATION SUPPORT SYSTEM FOR NEW PRODUCT DEVELOPMENT

ABSTRACT The current changing market trends have made enterprises enthusiastically pursue the innovation of their products or services. Due to the short life cycle of products and the changing preferences of customers, an enterprise needs to dynamically utilize its resources so as to deliver the new products or services in time to meet the market trends. For the complex process of a new product development, this paper proposes a prototype of the negotiation support system that assists decision makers of an enterprise in coordinating with each other, and finally reaching the solutions. A genetic algorithm (GA) is used to develop the searching algorithm, and to generate all possible candidate solutions for the evaluation process performed by the decision makers. With the aid of the solution sets, the decision makers may choose the most suitable solution based on current business scenario and demands. Alternatively, if the decision makers do not reach a consensus, the system can assist decision makers in providing a negotiation mechanism to reach their consensus. Consequently, it speeds up the decision making process in new product development so as to shorten the product development time and enhance the competitive capability of the enterprises.
