Static Analysis Of Structural Members, Amani Calderon, Alexis Villalona, Farhad Alinaghizadeh Dec 2019

Static Analysis Of Structural Members, Amani Calderon, Alexis Villalona, Farhad Alinaghizadeh

Publications and Research

This research is devoted to statics analysis of structural members under mechanical loads. Static analysis of beams under uniform transverse mechanical loads is presented. The beams are supported by simply supported boundary condition at both sides. The equilibrium equation of the beams is obtained and solved using analytical method and numerical method. The numerical method employed in this work is generalized differential quadrature (GDQ) method. The type of differential quadrature method used for numerical solution is the polynomial-based GDQ method. The differential equation is discretized into algebraic equations based on the GDQ technique. The algebraic equations are then solved to ...


Green Roof System Integrated Soil Methods, Jude R. Vallon, Ivan L. Guzman Dec 2019

Green Roof System Integrated Soil Methods, Jude R. Vallon, Ivan L. Guzman

Publications and Research

Large metropolitan areas like NYC are seeking to integrate sustainability into retrofitting buildings for the development of green infrastructure. Among the many environmental issues of urbanization, the UHI (urban heat island) effect and storm water runoff are of particular interest when it comes building structures. Individual buildings can contribute towards mitigating these effects with implementation of vegetative rooftops, i.e. Green Roofs. Commercial buildings are currently receiving government incentives and new constructions are required to include green roof installations. However, if existing buildings are considering the addition of a green roof on an existing roof, they have to factor in ...


Low-Cost Near Infrared Diffuse Optical Imaging System, Mohammed Z. Shakil, Chen Xu Dec 2019

Low-Cost Near Infrared Diffuse Optical Imaging System, Mohammed Z. Shakil, Chen Xu

Publications and Research

Diffuse Optical Tomography (DOT) and Optical Spectroscopy using near-infrared (NIR) diffused light has demonstrated great potential for the initial diagnosis of tumors and in the assessment of tumor vasculature response to neoadjuvant chemotherapy. The NIR technique utilizes intrinsic hemoglobin contrast, which is directly related to tumor angiogenesis development, a key process required for tumor growth and metastasis. The NIR diffuse tomography holds great promise in distinguishing early-stage invasive breast cancers from benign lesions. This technique also provides insight into tumor metabolism and tumor hypoxia, important indicators of tumor response to various forms of therapy. Currently, the high cost of the ...


Static Analysis Of Circular Plates Under Mechanical Loads, Harpreet Lalia Dec 2019

Static Analysis Of Circular Plates Under Mechanical Loads, Harpreet Lalia

Publications and Research

In this research statics analysis of circular plates is performed using SolidWorks.

Circular plates with different material properties, thickness to radius ratios, and boundary conditions under mechanical loads are modeled and analyzed in SolidWorks.

The results are obtained for deflections of circular plates under uniform and point loads.

A three-dimensional (3D) model of circular plates is first created in SolidWorks. Then the material properties, mechanical loads and boundary conditions are defined for the plate.

It is found deflection of plates is depended on magnitude of mechanical loads, geometrical parameters, boundary conditions and material properties. Responses of SolidWorks for deflections of ...


Fabrication And Imaging Characterization Of Poly (Dimethyl Siloxane)/Sic Nano-Fillers Samples As Model Biomaterials, Tetiana Soloviova, Viorica Gutu, Zoya Vinokur, Akm S. Rahman, Subhendra Sarkar Dec 2019

Fabrication And Imaging Characterization Of Poly (Dimethyl Siloxane)/Sic Nano-Fillers Samples As Model Biomaterials, Tetiana Soloviova, Viorica Gutu, Zoya Vinokur, Akm S. Rahman, Subhendra Sarkar

Publications and Research

Biopolymers are being developed with embedded nanostructures for in vivo drug delivery to treat various diseases including cancers. In the current project we developed fabrication steps to prepare two biopolymers, poly di-methoxy siloxane (PDMS) with 0-0.9 vol% of SiC nano whisker (fillers) followed by non- destructive characterization. Optical reflection microscopy (5-100X) was performed to ensure loading and distribution of increasing SiC content. Optical microscopy showed progressively higher SiC distribution as filler loading was increased from 0-0.9 vol%. X-ray imaging at low kV (kilovoltage) and low mAs (milliamperage per second) were optimized to allow distinction between filled PDMS with ...

Biofuels From Waste To Road Transport, Marine Peyrot, Johnny Stuen, Robbie Venderbosh, Wolfgang Hofer, Hank Vleeming, Mauro F. Sgroi, Yves Schuurman, Duncan Akporiaye

Pyroliq 2019: Pyrolysis and Liquefaction of Biomass and Wastes

Biofuels from Waste to Road (WASTE2ROAD) is an EU funded project under the Grant Agreement No. 818120 within the LC-SC3-RES-21-2018 call, “Development of next generation biofuels and alternative renewable fuel technologies for road transport”, as a Research and Innovation Action of the European Union’s Horizon 2020 Programme. The project started in the fall 2018 and will run for 4 years.

In 2014, total waste production in the EU amounted to 2.5 billion tons. From this total only a limited (albeit increasing) share (36%) was recycled, while the rest was landfilled or burned, of which some 600 million tons ...


3d Printed Smart Mobile, Bingfang Chen May 2019

3d Printed Smart Mobile, Bingfang Chen

Publications and Research

The goal of this research project is to design and build a prototype of a smart mobile robot to participate and compete in IEEE Micro-mouse and similar competitions. The robot has to find its way out of a maze as quickly as possible, by exploring and learning the paths in the maze. 3D printing technology will be used to build a lightweight robot frame so that it can move at a fast speed.

The Core Of Social Network Modeling: Industrial Engineering., Shannon C. Roberts, Chaitra Gopalappa, Nazanin Nazanin Jan 2019

The Core Of Social Network Modeling: Industrial Engineering., Shannon C. Roberts, Chaitra Gopalappa, Nazanin Nazanin

Science and Engineering Saturday Seminars

Networks are abound in our everyday lives, from disaster response networks to cellular networks to social networks. In this workshop, we will introduce the different types of networks and how Industrial Engineering is used to model these networks. Next, we will describe current social network modeling research done at UMass. Finally, we will delve into hands-on activities that include social network analysis, such as the clustering of people into groups, and modeling of the spread of ideas in a social network, such as how tweets spread on Twitter.
