Hatti and Team Win Startup Competition

by Electrical and Computer Engineering 

Nagesh Hatti (ECE) was the lead of a startup team that took first place in a virtual entrepreneurial startup event focusing on Education, held earlier this month. The Techstars StartUp weekend was hosted virtually from São Judas University in São Paulo, Brazil. 

Hatti and team pitched “Inter-Self” a mobile-based app that focuses on the emotional health of students, combined with their interaction with fellow students, during projects and assignments. 

Hatti said the objective of their idea is to provide a feedback mechanism so instructors are aware of the overall emotional health of students, and then use that as an input to their instruction. 

Techstars Startup Weekend, in partnership with Google for Startups, is a 54-hour event created for entrepreneurs of all kinds. “It was an intense but rewarding experience,” Hatti said. “There was a lot of support and encouragement to come up with new ideas and execute on them.” 

Hatti said that many of the mentors participating in Techstars startup weekend were successful entrepreneurs who started companies at similar events.

Poster: A Secure Plausibly Deniable System for Mobile Devices against Multi-snapshot Adversaries
Authors: Bo Chen, Niusen Chen
Abstract: Mobile computing devices have been used broadly to store, manage and process critical data. To protect confidentiality of stored data, major mobile operating systems provide full disk encryption, which relies on traditional encryption and requires keeping the decryption keys secret. This however, may not be true as an active attacker may coerce victims for decryption keys. Plausibly deniable encryption (PDE) can defend against such a coercive attacker by disguising the secret keys with decoy keys. Leveraging concept of PDE, various PDE systems have been built for mobile devices. However, a practical PDE system is still missing which can be compatible with mainstream mobile devices and, meanwhile, remains secure when facing a strong multi- snapshot adversary. This work fills this gap by designing the first mobile PDE system against the multi-snapshot adversaries.

Poster: Incorporating Malware Detection into Flash Translation Layer
Authors: Wen Xie, Niusen Chen, Bo Chen
Abstract: OS-level malware may compromise OS and obtain root privilege. Detecting this type of strong malware is challeng- ing, since it can easily hide its intrusion behaviors or even subvert the malware detection software (or malware detector). Having observed that flash storage devices have been used broadly by computing devices today, we propose to move the malware detector to the flash translation layer (FTL), located inside a flash storage device. Due to physical isolation provided by the FTL, the OS-level malware can neither subvert our malware detector, nor hide its access behaviors from our malware detector.

The 41st IEEE Symposium on Security and Privacy was sponsored by the IEEE Computer Society Technical Committee on Security and Privacy in cooperation with the International Association for Cryptologic Research. The Symposium was May 18-20, 2020, and the Security and Privacy Workshops were May 21, 2020.

Nathir Rawashdeh to Present Paper at Advances in Mechanical Engineering Conference

Nathir Rawashdeh

A conference paper co-authored by Nathir Rawashdeh (CC/MERET), has been accepted for presentation and publication at the 5th International Conference on Advances in Mechanical Engineering, December 17-19, 2019, in Istanbul, Turkey.

The paper is entitled, “Effect of Camera’s Focal Plane Array Fill Factor on Digital Image Correlation Measurement Accuracy.” Co-authors are Ala L. Hijazi of German Jordanian University, and Christian J. Kähler of Universität der Bundeswehr München.

Abstract: The digital image correlation (DIC) method is one of the most widely used non-invasive full-field methods for deformation and strain measurements. It is currently being used in a very wide variety of applications including mechanical engineering, aerospace engineering, structural engineering, manufacturing engineering, material science, non-destructive testing, biomedical and life sciences. There are many factors that affect the DIC measurement accuracy where that includes; the selection of the correlation algorithm and parameters, the camera, the lens, the type and quality of the speckle pattern, the lightening conditions and surrounding environment. Several studies have addressed the different factors influencing the accuracy of DIC measurements and the sources of error. The camera’s focal plane array (FPA) fill factor is one of the parameters for digital cameras, though it is not widely known and usually not reported in specs sheets. The fill factor of an imaging sensor is defined as the ratio of a pixel’s light sensitive area to its total theoretical area. For some types of imaging sensors, the fill factor can theoretically reach 100%. However, for the types of imaging sensors typically used in most digital cameras used in DIC measurements, such as the “interline” charge coupled device CCD and the complementary metal oxide semiconductor (CMOS) imaging sensors, the fill factor is much less than 100%. It is generally believed that the lower fill factor may reduce the accuracy of photogrammetric measurements. But nevertheless, there are no studies addressing the effect of the imaging sensor’s fill factor on DIC measurement accuracy. We report on research aiming to quantify the effect of fill factor on DIC measurements accuracy in terms of displacement error and strain error. We use rigid-body-translation experiments then numerically modify the recorded images to synthesize three different types of images with 1/4 of the original resolution. Each type of the synthesized images has different value of the fill factor; namely 100%, 50% and 25%. By performing DIC analysis with the same parameters on the three different types of synthesized images, the effect of fill factor on measurement accuracy may be realized. Our results show that the FPA’s fill factor can have a significant effect on the accuracy of DIC measurements. This effect is clearly dependent on the type and characteristics of the speckle pattern. The fill factor has a clear effect on measurement error for low contrast speckle patterns and for high contrast speckle patterns (black dots on white background) with small dot size (3 pixels dot diameter). However, when the dot size is large enough (about 7 pixels dot diameter), the fill factor has very minor effect on measurement error. In addition, the results also show that the effect of the fill factor is also dependent on the magnitude of translation between images. For instance, the increase in measurement error resulting from low fill factor can be more significant for subpixel translations than large translations of several pixels.

Soner Onder Presents Keynote at SAMOS XIX

Soner Onder

Soner Onder (SAS), professor of computer science, presented a keynote lecture July 8, 2019, at the International Conference on Embedded Computer Systems: Architectures, Modeling and Simulation (SAMOS XIX) on Samos Island, Greece, which was held July 7-11. Onder’s talk was titled, “Form Follows Function: The Case for Homogeneous Computer Architectures.” Onder also participated in the conference’s “The Annual Open Mike Panel.”

Keynote Lecture Abstract: ”Form follows function” is a principle associated with 20th-century modernist architecture and industrial design which says that the shape of a building or object should primarily relate to its intended function or purpose”[2]. For best performance in computer architecture, form must follow function as well. What are form and function in computer architecture? Form is easy to understand and interpret in its dictionary meaning; Function is not so clear-cut. In this talk, I will start with a simple problem, an algorithm, and a basic program representation that will be interpreted by the machine, and show that delivering high performance rests on solving only a handful, but fundamentally difficult problems. I will argue that the mere existence of domain specific solutions that general purpose computing cannot match in performance is a testament that the general purpose computing is ”not general enough”. What makes an architecture ”not general enough” is not the architecture itself, but rather the mismatch between the function its form had followed and the actual semantics of programs. To illustrate the point, I will challenge the widely understood interpretation of instruction-level parallelism (ILP) as ”single-thread performance”, and show that this interpretation is too short-sighted. We can efficiently exploit all types of available parallelism, including process-level, thread-level and data level parallelism, all at the instruction-level, and this approach is both feasible and necessary to combat the complexity that is plaguing our profession. I will then discuss why an executable single-assignment program representation [1] may be the ultimate function whose implementations may result in homogeneous general purpose architectures that can potentially match the performance of accelerators for specific tasks, while exceeding the performance of any accelerator traditional architecture combination for general tasks. I will conclude by discussing our results with Demand-driven Execution (DDE), whose form follows this single-assignment program representation.

About SAMOS (from SAMOS is a unique conference. It deals with embedded systems (sort of) but that is not what makes it different. It brings together every year researchers from both academia and industry on the quiet and inspiring northern mountainside of the Mediterranean island of Samos, which in itself is different. But more importantly, it really fosters collaboration rather than competition. Formal and intensive technical sessions are only held in the mornings.A lively panel or distinguished keynote speaker ends the formal part of the day, and leads nicely into the afternoons and evenings — reserved for informal discussions, good food, and the inviting Aegean Sea. The conference papers will be published by Springer’s Lecture Notes in Computer Science – LNCS and will be included in the DBLP Database.
