A Survey of Interaction Techniques and Devices for Large High Resolution Displays

Innovations in large high-resolution wall-sized displays have been yielding benefits to visualizations in industry and academia, leading to a rapidly growing increase of their implementations. In scenarios such as these, the displayed visual information tends to be larger than the users field of view, hence the necessity to move away from traditional interaction methods towards more suitable interaction devices and techniques. This paper aspires to explore the state-of-the-art with respect to such technologies for large high-resolution displays

Essays on retail pricing

Most empirical literature on Walmart Supercenters quantifies the price effect of Supercenter entries using lower frequency data (annual or monthly) and does not take into account finer geographical detail of retail markets experiencing Walmart entries. There is also very little empirical research on quantifying the impact of secondary entries by Walmart Supercenters in retail markets. We fill this gap by quantifying the price effect of secondary Supercenter entries into a specific retail market: Columbia, Missouri. We make use of hand-collected weekly price data spanning four time periods from 2006 to 2008 and do not find any evidence of negative price effect either in immediate term or in medium term following the opening of the two Walmart Supercenters in Columbia, Missouri. This result holds for all types of products and for grocery stores of all sizes. There is a dearth of economic literature that quantifies price pass-through following minimum-wage changes. We fill this gap by using a dataset of U.S minimum-wage histories from 1993-2012 along with micro-level price data on specific food products in the fast-food industry during the same time period. We find evidence that minimum-wage increases are associated with statistically significant increases in fast-food prices. However, we also find evidence that minimum-wage hikes are in fact endogenous to prevailing costs of living and correlated with the error term. This endogeniety bias suggests that that actual minimum-wage price elasticity may be much smaller than as estimated in earlier empirical literature on the subject

Giant adrenal endothelial cyst associated with acute and chronic morbidity in a young female: a case report

Adrenal cysts are rare clinical entities that can present as acute abdomen through rupture and internal hemorrhage as well as chronic symptoms such as gastrointestinal disturbances. A 20-year-old girl presented to our hospital with a 4-years history of abdominal pain and diarrhea. Ultrasound of the abdomen revealed a cystic area measuring 10 × 10 cm between the spleen and left kidney. Computed tomography scan showed a large cystic, homogeneous mass measuring 12.8 × 9.5 × 9.4 cm in the left hypochondrium with most likely origin from the left adrenal gland. Limited work up for hormone hypersecretion was negative. The patient was then encountered in the emergency room with an acute abdomen secondary to intracystic hemorrhage. A laparotomy with left adrenalectomy was performed. Final pathology showed a benign adrenal endothelial cyst. Post-operatively, the patient's long standing complaints of diarrhea and abdominal pain completely resolved. Surgical resection appears a safe and reasonable management strategy in a patient with intracystic hemorrhage of adrenal cyst

How regional authorities can achieve economic development through investments in the logistics sector

Thesis (M. Eng. in Logistics)--Massachusetts Institute of Technology, Engineering Systems Division, 2004.Includes bibliographical references (leaves 42-43).Lessons for how a regional authority should develop its logistics sector are learned through case studies on four areas (section 2). In addition, a "logistics attractiveness" ranking framework is developed and applied (section 3). A learning from the case studies is that a regional authority plays an active role. It leads the development and sustained progress of logistics related activity either directly or through facilitation. Another insight is that training of people and academic research activity in the field of logistics is accompanying the local development of the logistics sector. This is done somewhat independently by the universities but the authorities are playing a supporting role. Countries found to rank high in their overall logistics attractiveness are generally competitive in infrastructure, information & communication technology (ICT) and ease of doing business (EOB. In addition to the case studies and 'logistics attractiveness' ranking framework this thesis provides an overview of other areas around the world where new logistics park type development activity is found to be taking place (section 4).by Taimur Khan.M.Eng.in Logistic

Assesment of Salinity and Alkalinity of Groundwater and It Relation to the Geochemical Propersties of Soil in a Specific Site of Lasbela Region

The study was conducted on assessment of salinity and alkalinity of groundwater and it relation to the geochemical properties of soil in a specific site of Lasbela region during 2013-14. Field data was collected through questionnaires. Water and soil samples were collected from 32 randomly selected sites. Both soil and water were analyzed for Electrical Conductivity and SAR by following standard procedures. The general trend line showed that soil salinity increased with an increase in water salinity. ECw has significantly affected the soil properties sites. The Alkanity levels both at water and soil differ significantly with each other. Alkanity of soil is increasing with the application of sodic water. Alkanity levels of groundwater used for irrigation of crops didn’t have a significant relation for soil Alkanity at different sites of the study area. There is an inverse relationship between Electrical conductivity and Sodium Adsorption Ratio. The saline groundwater quality from the irrigation to the whole region is although causing reduction in soil alkanity but it is causing lesser impact when compared to the individual sites in the study area. Keywords: Salinity, Alkanity, Sodium Absorption Ratio, Electrical Conductivity, Assessmen

Visualization and Evolution of Software Architectures

Software systems are an integral component of our everyday life as we find them in tools and embedded in equipment all around us. In order to ensure smooth, predictable, and accurate operation of these systems, it is crucial to produce and maintain systems that are highly reliable. A well-designed and well-maintained architecture goes a long way in achieving this goal. However, due to the intangible and often complex nature of software architecture, this task can be quite complicated. The field of software architecture visualization aims to ease this task by providing tools and techniques to examine the hierarchy, relationship, evolution, and quality of architecture components. In this paper, we present a discourse on the state of the art of software architecture visualization techniques. Further, we highlight the importance of developing solutions tailored to meet the needs and requirements of the stakeholders involved in the analysis process

DESIGN AND DEVELOPMENT OF NOISE SUPPRESSION SYSTEM FOR DOMESTIC GENERATORS

Increase in demand for standby power sources and disruption in power supply has increased the use of generators manifold for domestic and industrial consumers leading to objections on their use concerning noise pollution. The work presented here aims to focus on how generator set noise is propagated, controlled and reduced to a limit as defined by domestic laws. The presented work is in fact a feasibility of a simple and effective design of an acoustic enclosure for portable generators aims at reducing the radiated noise. This effort is a multi-disciplinary work that comprises acoustics, heat transfer and material science. Heat generation and requirement of cooling air leads to a heat transfer model with internal forced convection. The design is a balance of noise control and thermal management. Noise generating areas have been identified and conventional passive noise control techniques have been used to control and reduce the noise. Acoustic barriers and insulation are used to control the noise propagation at its transmission path. In the conclusion comparison and results of noise are plotted using sound measuring techniques and devices as well as the thermal profiles of cylinder head are compared with and without canopy

Pathogenesis, diagnosis and management of primary melanoma of the colon

<p>Abstract</p> <p>Background</p> <p>Melanomas within the alimentary tract are usually metastatic in origin. On the other hand, primary melanomas of the gastrointestinal tract are relatively uncommon. There are several published reports of melanomas occurring in the esophagus, stomach, small bowel, and anorectum. The occurrence of primary melanoma of the colon has, however, only been rarely reported. The optimum modus operandi for the management of primary colonic melanoma remains nebulous due to the limited number of reports in literature.</p> <p>Methods</p> <p>A comprehensive search of Medline, Cochrane and Highwire was performed using the following keywords: 'melanoma', 'malignant melanoma', 'primary melanoma', 'colon', 'gastrointestinal tract', 'alimentary tract', 'digestive tract', and 'large bowel'. All patients with primary melanoma localized to the colon were included in the review. Patients with metastatic melanomas to the gastrointestinal (GI) tract and primary melanomas localized to the GI tract in anatomic locations other than colon were excluded.</p> <p>Results</p> <p>There have been only 12 reported cases of primary melanoma of the colon to date. The average age of patients on presentation was 60.4 years without any significant gender predilection. Right colon (33%) and cecum (33%) were the most common sites for the occurrence of primary colonic melanoma while abdominal pain (58%) and weight loss (50%) were the most common presenting complaints. Colonoscopy is the most reliable diagnostic investigation and offers the additional advantage of obtaining tissue for diagnosis. S-100 and HMB-45 are highly sensitive and specific for the diagnosis of this malignancy. For primary colonic melanomas that have not metastasized to any distant parts of the body, surgical resection with wide margins appears to be the treatment of choice. Although the management was individualized in every case, most of the authors preferred traditional hemicolectomy as the favored surgical approach. Chemotherapeutic agents including interferons, cytokines, biological agents and radiation therapy for brain metastases have been reported as adjuvant and palliative options while considering malignant melanomas in general. The average recurrence-free interval was 2.59 years. Nine of the 12 reports documented follow-up in their patients. Two of these 9 (22.2%) patients died.</p> <p>Conclusions</p> <p>Primary melanoma of the colon is a rare clinical entity. Whenever a seemingly primary melanoma is detected in an atypical location such as the colon, it is prudent to conduct a thorough clinical investigation to consider the possibility of metastatic disease. Further studies are needed to document the long term follow-up, survival advantage and safety of the management approaches employed in patients with primary colonic melanoma. Based on current data, surgical resection appears to be appropriate management for primary colonic melanomas; unless the disease has metastasized to distant sites where surgery may have a limited palliative role.</p
