Secure Computation in Decentralized Systems by Zyskind, Guy

“…We develop a highly efficient Threshold ECDSA protocol that runs in the server-aided MPC model. Perhaps more importantly, we revisit the server-aided MPC model itself, which sits somewhere between the dishonest and honest-majority MPC paradigms, and show that a confidential smart contract is a real-world realization of the server in this model. …”

Prediction of stable perovskite quantum dots (QDs) using machine learning (ML) algorithms by Cheong, Ivan

“…We demonstrated that there is a relationship of the composition and ionic radius with its photoluminescence quantum yield (PLQY), however the highest R2 scores of 0.49 produced by the XGBoosting regression model were not good enough for running a useable prediction. Falling back to literature of known understanding of the photoluminescence property, suggested that the nanocrystal’s surface ligands interface has a substantial impact on optical properties. …”

Application and control for virtual synchronous generators by Guo, Yian

“…Continuing the exploration to align with real-world conditions more closely, the paper delves into the operation of two VSGs running in parallel. Initially, a small-signal model for the parallel operation of two inverters was developed. …”

Three essays on corporate finance by Zou, Kunru

“…The endogeneity tests, which include an instrumental variable approach based on supply-side determinants of loan covenants and two quasi-natural experiments respectively based on SFAS 160 and anti-recharacterization statutes, support a causal relation running from covenant intensity to CSR. Further analyses reveal that the negative CSR effect of covenant intensity is more pronounced when the creditors have higher bargaining power, when loans outstanding are closer to maturity, and when the conflict of interest between creditors and other stakeholders is greater. …”

Comparison of transport methodologies on near-field pollutant dispersion in urban environments using CFD by Tee, Clarence Wei Tat

“…With regards to computational efficiency, the passive scalar transport model has proven to be consistently more efficient compared to the multi-species transport model. Time taken for running simulations using the passive scalar transport model is observed to be three times shorter compared to using the multi-species model.…”

Server allocation for massively multiplayer online cloud games by Zhao, Meiqi

“…Massively Multiplayer Online Cloud Game (MMOCG) is a combination of cloud gaming and Massively Multiplayer Online Game (MMOG). Running MMOGs on the cloud can reduce the cost for the players, attract potential players, and meet the nowadays preference of mobile devices. …”

Efficient optimization of network metrics in large uncertain graphs by Saha, Arkaprava

“…The proposed solution improves the existing filtering-and-verification framework by coupling Dijkstra’s algorithm with Monte Carlo sampling to reduce the running time by some orders of magnitude, with end-to-end accuracy guarantees. …”

Task allocation and scheduling for distributed job execution by Guan, Yitong

“…Efficiency and fairness are two important considerations for sharing resources among concurrently running distributed jobs. In this thesis, we focus on the efficiency and fairness aspects of resource allocation in distributed job execution and study three specific c problems, including task assignment and scheduling for improving efficiency of distributed job execution, max-min fair resource allocation for distributed job execution, and generalized max-min fair resource allocation for jobs with tasks executable at multiple sites. …”

Dynamic drug combination methods for suppressing bacterial antibiotics resistance adaptation by Bhone, Myint Kyaw

“…Therefore, there is a concern that MRSA would gradually become fully-resistant to vancomycin in the near future and newer treatment strategies or compounds that can effectively cure S. aureus related infections should be well underway before our last antibiotic runs out. Plants have been naturally used since the ancient times as medicine and still many plant compounds can be found in the treatment of major ailments such as malaria and cancer. …”

Improving the productivity of high-level synthesis by advancing reuseability and verifiability by Yang, Liwei

“…However, HLS tools are different from typical large-scale software; we must verify that the HLS tool output is always functionally correct RTL, not just that the HLS tool runs to completion without error. Therefore, the verification process of the functional correctness of HLS tools has also become a bottleneck that defers the enhancement of QoR, thus preventing HLS from achieving further improved productivity. …”

Optimized GPU algorithms for sparse data problems by Pham, Nguyen Quang Anh

“…Compared to existing GPU coloring algorithms, our first algorithm uses 1.1 − 4.3× fewer colors on average, while the second algorithm uses slightly more colors but runs 2.7 − 4.3× faster than other algorithms. The techniques we introduced are the basis for our ongoing work on GPU sparse matrix and graph algorithms, as we seek to bridge the gap between the performance of sparse and dense data algorithms on GPUs.…”

Combinatorial algorithms for scheduling jobs to minimize server usage time by Ren, Runtian

“…The Flexible Job Scheduling problem aims at determining the starting times of flexible jobs that do not have to be started immediately at their arrivals to minimize the span of all the jobs, where the span is the time duration in which at least one job is running. In the non-clairvoyant online setting, we first show that no deterministic online scheduler can achieve a competitive ratio less than µ. …”

21W.747 Rhetoric, Fall 2002 by Strang, Steven M.

“…At its worst, however, rhetoric is used unethically by people to manipulate us instead of enlightening us, to spread propaganda instead of seeking truth, to make palatable those ideas and products whose adoption actually runs counter to our best interests. Understanding rhetoric, then, is our best defense against its abusers-- e.g., political "spin doctors," advertisers, demagogues, apologists for immoral business practices, and hate mongers. …”
