Rapid prototyping of small size objects

The commercialization of new products integrating many functions in a small volume requires more and more often the rapid prototyping of small high‐resolution objects, having intricate details, small openings and smooth surfaces. To give an answer to this demand, the stereolithography process has started to evolve towards a better resolution: the “small spot” stereolithography technology allows to reach a sufficient resolution for the manufacturing of a large range of small and precise prototype parts. Microstereolithography, a technique with resolution about an order of magnitude better than conventional stereolithography, is studied by different academic research groups. The integral microstereolithography machine developed at the Swiss Federal Institute of Technology in Lausanne is described in this paper, and potential applications are presented. The resolutions of conventional, small spot and microstereolithography technologies are compared and the potential of the microstereolithography technique is shown for the manufacturing of small and complex objects.

Accurate Detection of Human in the Presence of Occlusion

This paper describes a general method to detect humans in presence of occlusion in images. The main aim of this work is to introduce a general method for automatic, accurate and robust detection of human figures in the presence of partial occlusion. Current methods for handling occlusion lack generalization, either because additional information is required (coming from manual annotations of the parts or from other sensors), or they are tied to a specific object class. So to overcome this, proposed a method which does not require manual labeling of body parts, defining any semantic spatial components, or using additional data coming from motion or stereo. The experiments are performed on large datasets like INRIA person dataset, the Daimler Multicue dataset, and a new challenging dataset, called PobleSec, in which a considerable number of targets are partially occluded. The different approaches are evaluated at the classification and detection levels for both partially occluded and non-occluded data.The datasets used in our experiments have been made publicly available for benchmarking purposes.
A 2.4 GHz antenna for medical implanted communications

There is a huge interest of tissue implanted devices for wireless medical applications with wider bandwidth as medicine day by day and more and more is associated with electronics and electromagnetics. The current Medical Implant Communications Service (MICS) with frequency range of 402–405 MHz is not suitable to transfer image data due to bandwidth and regulation limitation. A key component of wireless implanted device is an antenna, and there are several issues to consider while designing an in-body antenna, including power consumption, size, frequency, biocompatibility and the unique RF transmission challenges posed by the human body. This paper mainly deals with an implantable antenna design for the frequency band of 2.4 GHz.
Ethnographic Blogging: Reflections on a Methodological Experiment

Abstract This paper describes how a weblog was utilized as a major component in a long-term, multi-site ethnography with both “virtual” and physically situated research components. “Ethnographic blogging” describes not only the act of writing on a website and hoping that someone will read it, but the process of regularly maintaining a blog, and the modes of interaction and observation that this process gradually enables. In my own study of self-identified ‘geeks’ and ‘nerds,’ ethnographic blogging involved traversing news sites, forums, and other blogs for relevant content, leading to opportunities for dialogue with other bloggers and readers; establishing a persona online as a researcher, which has encouraged subjects to invite me to public and private discussions about their culture and identities; and bringing together online subjects from multiple physical sites, among other opportunities. My own experience of integrating a blog into ethnographic research was largely experimental, though I offer these reflections to encourage researchers to consider what alternative means of qualitative analysis online may have to offer us.
Modelo hierárquico bayesiano na determinação de associação entre marcadores e QTL em uma população F2

The purpose of QTL mapping is to identify the position of loci controlling quantitative traits in the genome, that is, to identify the chromosomes and the locations in which the QTLs meet and, moreover, to estimate Its additive and dominance effects. To do this, a large number of molecular markers spread across the chromosomes that may be linked to these QTLs are used and, therefore, may be associated with phenotypic characteristics. Due to this, the statistical models have a high number of parameters to be estimated. However, it is expected that many of these markers will not be bound to QTL and thus some of these parameters will not be significant. The purpose of this work is to use a priori distribution that allow the incorporation of these non-QTLMarkers associations into the model, which together with the data information lead to the updating of the QTL-binding information. Two models were used: the first using the Lasso Bayesian shrinkage distribution (a priori) and the second Horseshoe Estimator. To verify the performance of the models were performed 1000 simulations referring to 10 scenarios, in which there was variation in the number of individuals, number of markers and heritability levels. It was observed that the proposed models have the ability to select the markers associated with QTL in all scenarios. The models were adjusted to grain yield data from progenies of a maize population, previously analyzed by other methodologies, to allow comparisons of methodologies. The computational implementation of the algorithms was done using the C language and executed in the statistical package R.
From template to anchors: transfer of virtual pendulum posture control balance template to adaptive neuromuscular gait model increases walking stability

Biomechanical models with different levels of complexity are of advantage to understand the underlying principles of legged locomotion. Following a minimalistic approach of gradually increasing model complexity based on Template & Anchor concept, in this paper, a spring-loaded inverted pendulum-based walking model is extended by a rigid trunk, hip muscles and reflex control, called nmF (neuromuscular force modulated compliant hip) model. Our control strategy includes leg force feedback to activate hip muscles (originated from the FMCH approach), and a discrete linear quadratic regulator for adapting muscle reflexes. The nmF model demonstrates human-like walking kinematic and dynamic features such as the virtual pendulum (VP) concept, inherited from the FMCH model. Moreover, the robustness against postural perturbations is two times higher in the nmF model compared to the FMCH model and even further increased in the adaptive nmF model. This is due to the intrinsic muscle dynamics and the tuning of the reflex gains. With this, we demonstrate, for the first time, the evolution of mechanical template models (e.g. VP concept) to a more physiological level (nmF model). This shows that the template model can be successfully used to design and control robust locomotor systems with more realistic system behaviours.
Novel substrate integrated waveguide filters and circuits

The main work in this thesis is to explore novel microwave filters with more compact size and improved performance by taking advantage of new substrate integrated waveguide (SIW) structures, such as the ridge substrate integrated waveguide, half mode substrate integrated waveguide (HMSIW) and SIW with complementary split ring resonators (CSRRs). This thesis therefore presents the following topics: 1. Development of a design strategy to convert from a conventional ridge waveguide configuration with solid walls to the SIW counterpart, and the design of a bandpass filter based on the ridge SIW with the proposed design method. 2. Development of a ridged HMSIW to reduce the physical size of the HMSIW by loading the HMSIW with a ridge, and application of the ridged HMSIW to the design of compact bandpass filters. 3. Development of a broadside-coupled complementary split ring resonator and a capacitively-loaded complementary single split ring resonator to reduce the size of SIW with conventional CSRRs, and application of the proposed modified structures in the design of SIW and HMSIW filters with improved compactness and performance. 4. Investigation of the application of the complementary electric-LC (CELC) resonator in SIW filters with improved stopband performance, and development of a cascaded CELC resonator to further enhance the out-of-band performance.
A survey of contractors’ corporate planning and financial budgeting

The authors found that contracting‐only firms were more vunerable in cases of inaccurate budgets; fluctuations in working capital could lead to the bankruptcy of a contractor who could not raise loans quickly. Two reasons were identified as the cause of inaccurate budgets: forecasting on an overall basis and the inability to take into account accurately variations in strategies and the environment.
The Role of 3D Printing in Medical Applications: A State of the Art

Three-dimensional (3D) printing refers to a number of manufacturing technologies that generate a physical model from digital information. Medical 3D printing was once an ambitious pipe dream. However, time and investment made it real. Nowadays, the 3D printing technology represents a big opportunity to help pharmaceutical and medical companies to create more specific drugs, enabling a rapid production of medical implants, and changing the way that doctors and surgeons plan procedures. Patient-specific 3D-printed anatomical models are becoming increasingly useful tools in today's practice of precision medicine and for personalized treatments. In the future, 3D-printed implantable organs will probably be available, reducing the waiting lists and increasing the number of lives saved. Additive manufacturing for healthcare is still very much a work in progress, but it is already applied in many different ways in medical field that, already reeling under immense pressure with regards to optimal performance and reduced costs, will stand to gain unprecedented benefits from this good-as-gold technology. The goal of this analysis is to demonstrate by a deep research of the 3D-printing applications in medical field the usefulness and drawbacks and how powerful technology it is.
Emotional Impact of Different Forms of Spatialization in Everyday Mediatized Music Listening: Placebo or Technology Effects?

Do the spatial cues conveyed by different audio playback technologies alter the affective experience of music listening or is this rather a matter of quality expectations leading to “placebo effects”? To find out, we conducted a 2-factorial between-subjects design study employing “spatialization type” (‘stereo headphones’ / ‘stereo loudspeakers’ / ‘live concert simulation’) and “spatial quality expectations” (‘yes’ / ‘no’) as independent experimental factors. 306 subjects rated the perceived intensity of emotional expression when listening to four different musical pieces as well as the overall audio quality. While we observed significant effects of spatialization type on perceived affective expressivity of music and spatial audio quality, expectation-related placebo effects affected perceived spatial audio quality only. Results are discussed in terms of their significance for music and media research.
Flow analysis and design optimization methods for nozzle afterbody of a hypersonic vehicle

This report summarizes the methods developed for the aerodynamic analysis and the shape optimization of the nozzle-afterbody section of a hypersonic vehicle. Initially, exhaust gases were assumed to be air. Internal-external flows around a single scramjet module were analyzed by solving the three dimensional Navier-Stokes equations. Then, exhaust gases were simulated by a cold mixture of Freon and Argon. Two different models were used to compute these multispecies flows as they mixed with the hypersonic airflow. Surface and off-surface properties were successfully compared with the experimental data. In the second phase of this project, the Aerodynamic Design Optimization with Sensitivity analysis (ADOS) was developed. Pre and post optimization sensitivity coefficients were derived and used in this quasi-analytical method. These coefficients were also used to predict inexpensively the flow field around a changed shape when the flow field of an unchanged shape was given. Starting with totally arbitrary initial afterbody shapes, independent computations were converged to the same optimum shape, which rendered the maximum axial thrust.
CURRENT SITUATION OF PEDESTRIAN ACCIDENTS AND RESEARCH INTO PEDESTRIAN PROTECTION IN JAPAN

According to statistics on traffic accidents in Japan; (1) approximately 60% of four-wheel vehicles involved in pedestrian accidents are passenger cars; (2) 70% of the pedestrians involved are struck by the front of the vehicle; and (3) 50% of the fatalities are 65 year-olds or older. The proportion of elderly persons to the total number of pedestrian fatalities is expected to continue to increase. The findings from in-depth case studies of 113 pedestrian casualties show that: (1) the severity and location of the impact on the pedestrian depend upon the body size of the pedestrian and the shape of the front of the car; and (2) the parts of a car most important for pedestrian protection are the bumper, the hood edge, and the hood top. Parametric studies were performed by using full-scale sled tests and computer simulations. Important results of these studies are: (i) The shape of the front of the car, particularly the hood edge height, greatly influences the pedestrian kinematics after the impact; and (ii) the influence of the force-deformation characteristics of the front of the car upon the pedestrian kinematics appears to be small, compared to the dependence on the shape of the front of the car.

MPPT Control by Using a U–P Curve for PMSG–Based Small Wind Turbines

AbstractThe permanent magnet synchronous generator (PMSG)–based small wind turbines (SWT) are studied in recent years because of their high reliability, high efficiency and low cost. To achieve maximum power point tracking (MPPT) without mechanical sensors and improve efficiency, a novel MPPT control method is proposed in this paper. Without measurement of the shaft speed, the conventional MPPT control strategy based on the ω–P curve does not work. However, it is possible to impose the relationship between the RMS of generator output voltage (U) and the output power (P) on the optimum operating points. The innovations focus on obtaining the U–P curve by relating the RMS of U to the shaft speed ω and designing the controller by using the control strategy based on the U–P curve. After building the whole model of the PMSG–based SWT, the RMS of U is calculated theoretically from the ω, and the U−P curve is obtained. The generator speed controller is designed by using the control strategy based on the U−P curv.
Checklist of critical success factors for building projects

Previous research has determined the existence of a set of critical project success factors that play an important role in the planning, design, and construction of successful building projects. The basic form of these success factors originated from the integrated building process model, and were then tested using a series of case‐history studies including a formal interview process. This paper presents a checklist that can be used by building professionals as a guideline in predicting the success of a project. The checklist is a management and planning tool for determining potential pitfalls that will permit corrective action before the occurrence of major problems. Items represented in the checklist include questions similar to the questions and categories initially used to gather information for the identification of the critical project success factors. The checklist was developed based on an atmosphere in which the building owner, contractor, and operator work together as a team to develop technique.
TSM Measures for Major Activity Centers

Transportation Systems Management (TSM) measures, originally conceived as a tool applicable on a region-wide scale, can be successfully applied at major activity centers to avoid, minimize or postpone the need for more capital-intensive transportation improvements. The results from two case studies (an urban university campus and a suburban industrial park/regional shopping center) are presented and analyzed to illustrate how traffic reduction and improved vehicular flow can be achieved by low-cost measures such as ride-sharing programs, parking management policies, transit service improvements, marketing and others. The effectiveness of the university's on-going program, which has reduced traffic generated by the campus by almost 8%, is assessed and a recommended expansion of the program which potentially can double this reduction by 1985 is described. While conditions at the suburban industrial park/shopping center are such that a traffic reduction of 4% to 10% is considered the upper limit of what can be achieved, a comprehensive TSM program for maximizing the efficiency of existing facilities was also developed and is described.
How successful firms go beyond aligning their IT strategy with business objectives

How successful companies go beyond aligning their IT strategy with business objectives. By Debangshu Goswami Submitted to the System Design and Management Program on May 07, 2010 in Partial Fulfillment of the Requirement for the degree of Master of Science in Engineering and Management Information technology (IT) is vital to growth of all organizations. But getting value out of IT has been challenging. The companies, which fail to align their IT strategy with business objectives struggle with low or mediocre return on their IT investment. On the other hand, the companies that achieve strategic alignment realize higher economic benefits. Successful companies go one step further and use IT to enable business. They differentiate themselves from their competitors using IT and forge alliances. But is there any formula for achieving strategic alignment? The research of past decade seem to suggest that there indeed is a trend among companies, who manage to achieve strategic alignment. The successful companies recognize IT's unique value and ensure that it generates value like other assets do. IT is not a mere support function in such organizations. IT not only serves the internal businesses of the company but it acts like a business in dealing with suppliers. The framework of Strategic Alignment Model (SAM) identifies this as the balance of internal and external domain. The model asserts that IT should be judged both in terms of external domain, which determines how the firm as whole is positioned in the market place and internal domain, which constitutes IT's internal policies and structures. In the internal domain, the emphasis is more on technology than on business, management or organizational issue. The effective utilization of IT requires alignment of IT strategy with business objectives. This assertion is validated by a case study of a three companies, who successfully achieved strategic alignment.

Multimodality through physical digital design

This paper aims to deliver a better understanding of the relationship between physical and virtual, two dimensional and three dimensional representations of form employed in the critical early stages of design. It will present initial findings from observation of practice into how designers move between these representations, and of the kind and quantity of information they choose to exchange between them. Informed by these findings, and in response to the emerging need for new methods of sketching and prototyping in the digital era, it will also present a new proposal for hybrid virtual/physical digital design practice based on a significant modification of previous approaches.
