Impact of Scaling Gate Insulator Thickness on the Performance of Carbon Nanotube Field Effect Transistors (CNTFETs)

As scaling down Si MOSFET devices degrade device performance in terms of short channel effects. Carbon nanotube field effect transistor (CNTFET) is one of the novel nanoelectronics devices that overcome those MOSFET limitations. The carbon nanotube field effect transistors (CNTFETs) have been explored and proposed to be the promising candidate for the next generation of integrated circuit (IC) devices. To explore the role of CNTFETs in future integrated circuits, it is important to evaluate their performance. However, to do that we need a model that can accurately describe the behavior of the CNTFETs so that the design and evaluation of circuits using these devices can be made. In this paper, we have investigated the effect of scaling gate insulator thickness on the device performance of cylindrical shaped ballistic CNTFET in terms of transfer characteristics, output characteristics, average velocity, gm/Id ratio, mobile charge, quantum capacitance/insulator capacitance, drive current (Ion), Ion / Ioff ratio, transconductance, and output conductance. We concluded that the device metrics such as Ion, Ion / Ioff ratio, transconductance, and output conductance increases with the decrease in gate insulator thickness. Also, we concluded that the gate insulator thickness reduction causes subthreshold slope close to the theoretical limit of 60 mV/decade and DIBL close to zero at room temperature.

Potatoes

Potatoes are harvested somewhere in the world every month of the year. They are grown in all 50 states, and, in the past, on most South Dakota farms. In the last 25 years, the South Dakota growing area has shifted to the northeastern part of the state, and individual potato acreages have expanded to provide major parts of farm incomes. The northeastern area has a sandy loam soil and a climate that is ideal for growing potatoes. Relatively high elevations cause the cool nights necessary for potato production, and rainfall is sufficient in most years. The potato grower has felt a greater impact of technology in the past 20 years than have most other crop producers. New machinery, such as mechanical seed cutters, harvesters, and unloaders have, for the most part, taken the heavy labor out of producing potatoes

Identification and characterization of the dominant thermal resistance in lithium-ion batteries using operando 3-omega sensors

Poor thermal transport within lithium-ion batteries fundamentally limits their performance, safety, and lifetime, in spite of external thermal management systems. All prior efforts to understand the origin of batteries' mysteriously high thermal resistance have been confined to ex situ measurements without understanding the impact of battery operation. Here, we develop a frequency-domain technique that employs sensors capable of measuring spatially resolved intrinsic thermal transport properties within a live battery while it is undergoing cycling. Our results reveal that the poor battery thermal transport is due to high thermal contact resistance between the separator and both electrode layers and worsens as a result of formation cycling, degrading total battery thermal transport by up to 70%. We develop a thermal model of these contact resistances to explain their origin. These contacts account for up to 65% of the total thermal resistance inside the battery, leading to far-reaching consequences for the thermal design of batteries. Our technique unlocks new thermal measurement capabilities for future battery research

Muskmelons

The muskmelon is a popular crop although not an easy one to grow in all parts of South Dakota. But in many localized areas it is grown in market and truck gardens as a specialty crop. Muskmelons are generally considered a warm-season crop. They require soil temperatures of at least 55° F; even below 60°F, growth is slow. Muskmelons are stunted by chilling temperatures (33° to 45°F) and are readily killed by frost

Bungalows and their Typology in the Colonial Town: Ambala Cantonment

‘Bungalow’ has been the most representative element of the built environment of colonialism. It is associated with Europeans; although it developed in India, both in terms of name and form. The evolution of this Anglo-Indian residential typology shows how this indigenous mode of shelter, that was adopted and adapted by the Europeans, fulilled the physical, social and political requirements of the mercantile and the administrative European oficers. Among the urban centers established by the British in India, Ambala Cantonment was an important station due to geographical and political reasons. This Anglicized town that settled in 1843 bears the elements of a typical cantonment and is worth scrutinizing as it possesses all three residential types; the bungalows, havelies and shophouses. The bungalows that evolved a century and a half ago were resultant of cultural and social collaboration of the ideologies of the Europeans and the indigenous. It cannot be denied that the bungalows gradually brought about change in the lifestyle habits of the indigenous and impacted their understanding of health, cleanliness and hygiene. This paper, as part of the study, focuses on the bungalows of Ambala Cantonment with respect to their planning philosophies and elements. The bungalow had developed as a typology by the time this Cantonment was established. Primarily similar, these bungalows differ in terms of layout, largely in the arrangement of their rooms and this study categorizes the bungalows on this criteria.

Internet of Things (IoT) and Changing Face of Project Management

Internet of Things (IoT) or Industrial Internet is a modern day catchword, which over the past few years has tremendously impacted numerous aspects of almost-all the advanced technology fields. IoT framework envisions transforming the everyday objects into intelligent systems, while working under a common infrastructure and by connecting the global network of devices and machines over the internet. Based on many underlying interdisciplinary ecosystems, like sensor network, embedded systems, big data platforms, cloud computing and service-oriented architecture; IoT projects are non-traditional in many ways. Such projects involve research and development phase, more technical work, are lengthy, require advanced skill sets and lacks well-defined business models. A recent alarming rate of IoT project failures provide incentive to look for project management philosophies, which would emphasize on more flexibility, agility, teamwork and a developing a strong technical framework. This thesis work provides overview of IoT concepts and through a systematic review of scholarly research papers, blogs, review articles, and other literature available online, it addresses the current managerial challenges for such projects. Finally, to solve this issue a focused survey was conducted and collected data was analyzed. Based on the responses from IoT professionals various suggestions are made, which can be used to improve management of such projects

“Reviving Twentieth-century Medical Legacy – The Case of Banarasi Dass Women’s Hospital, Sadar Bazaar, Ambala Cantonment, India”

One of the notable advancements of late 19th-early 20th century British India was the introduction of ‘western-style’ medical care for women. Located within confines of the colonial or princely enclaves, a number of women’s hospitals, staffed with trained British female doctors, were established under the Dufferin Fund. But the benefits of medicalised childbirth did not extend to commonplace Indian women. At this point of time, history was also made by certain philanthropic and nationalist individuals who made some pioneering efforts to extend benefits of medicalised childbirth to the vast neglected body of commonplace Indian women.The 48-bedded Banarsi Dass Hospital for Women, built in 1922 within the dense urban fabric of Ambala Cantonment, is one of the earliest of such pioneering structures. The architectural value of the building as seen in its ingenious spatial organization was devised to ensure generous access to sun and air, ensured thermal comfort in all seasons, a construction system representative of the era, and various ornamental elements that proclaim its ‘monumental’ status adds to its unique historic significance. Though the building is still in a good physical and structural condition, the advancement in medical world has rendered its infrastructure obsolete.In the present scenario, we tend to lose a significant landmark of 20th century development in India. This paper presents an analysis of the historic, societal and architectural value of the property, the reasons for its disuse and the design interventions proposed to restore the original societal and architectural status of this majestic historic building

Sutures versus staplers for skin closure in laparotomy patients: a prospective study

Background: Every surgeon wants cosmetically acceptable scars along with optimal healing. Good tissue union and cosmetically acceptable scars are vital for ideal surgical practice. A basic need for skin closure is a good approximation. Apart from cosmetically good scars, it is also necessary that the skin closure technique should be technically easy, speedy, economical and acceptable.Methods: The study was conducted on 100 patients on whom elective abdominal surgeries were performed. Patients were divided into two groups with 50 patients in each group after matching the parameters like age, co morbid conditions, using simple random sampling technique. All operations were performed by one consultant. In group A, Skin was approximated with vertical mattress sutures while in group B, staplers were used to close the wound.Results: The age of the patients varied from 16 to 85 years. The average time taken for skin closure for suture group (A) was found to be 300sec (±20.78) and for stapler group was found to be 120sec (±16.50) respectively. Wound infection was found in 10 patients (20%). In stapler group 4 (8%) and in suture group 6 Patients (12%) had post-operative wound infection.Conclusions: Cosmesis is essential and necessary in modern surgical practice. It also reflects surgical expertise
