Mukhopadhyay, Sandip (author), Bouwman, W.A.G.A. (author), Jaiswal, Mahadeo Prasad (author)The efficient delivery of government services to the poor, or Bottom of the Pyramid (BOP), faces many challenges. While a core problem is the lack of scalability, that could be solved by the rapid proliferation of platforms and associated ecosystems. Existing research involving platforms focus on modularity, openness, ecosystem leadership and...journal article 2019

Ren, Z. (author), Erkin, Z. (author)Blockchains is a special type of distributed systems that operates in unsafe networks. In most blockchains, all nodes should reach consensus on all state transitions with Byzantine fault tolerant algorithms, which creates bottlenecks in performance. In this paper, we propose a new type of blockchains, namely Value-Centric Blockchains (VCBs),...conference paper 2019

Vaandrager, Willem (author)In an increasing urbanizing world the need for efficient transportation methods is growing. Ridesharing, sharing a taxi trip with multiple passengers, has been proposed as an effective way to contribute towards solving the traffic problems that arise in city centers. Current solutions to the problem are often more focused on optimality, and a...master thesis 2018

Hosseinimehr, S.M. (author), Cusini, M. (author), Vuik, Cornelis (author), Hajibeygi, H. (author)We present an algebraic dynamic multilevel method for multiphase flow in heterogeneous fractured porous media (F-ADM), where fractures are resolved at fine scale with an embedded discrete modelling approach. This fine-scale discrete system employs independent fine-scale computational grids for heterogeneous matrix and discrete fractures,...journal article 2018

Konat, G.D.P. (author), Erdweg, S.T. (author), Visser, Eelco (author)Incremental build systems are essential for fast, reproducible software builds. Incremental build systems enable short feedback cycles when they capture dependencies precisely and selectively execute build tasks efficiently. A much overlooked feature of build systems is the expressiveness of the scripting language, which directly influences the...conference paper 2018

Choupani, R. (author)With the rapid improvements in digital communication technologies, distributing high-definition visual information has become more widespread. However, the available technologies were not sufficient to support the rising demand for high-definition video. This situation is further complicated when the network resources such as the available...doctoral thesis 2017

van der Hoeven, E. (author)Massively Multiplayer Online Games are played by millions of people from around the world who play together in large virtual environments. With sometimes even a million gamers playing the same game, the load on the virtual environments they play in needs to be distributed between servers to deal with this many players. Several techniques have...master thesis 2017

Kersten, W.C. (author), Diehl, J.C. (author), Crul, M.R.M. (author)Many global sustainable development issues affect large numbers of people, e.g. clean cooking. Most current projects focus on a specific use context, therefore do not scale well to new contexts and consequently do not reach enough beneficiaries. We present an approach, Context Variation by Design (CVD), in which insights from different contexts...journal article 2017

Tohidian, M. (author), Madadi, I. (author), Staszewski, R.B. (author)The zero/low intermediate frequency (IF) receiver (RX) architecture has enabled full CMOS integration. As the technology scales and wireless standards become ever more challenging, the issues related to time-varying dc offsets, the second-order nonlinearity, and flicker noise become more critical. In this paper, we propose a new architecture of...journal article 2017

Tene, M. (author), al Kobaisi, MS (author), Hajibeygi, H. (author)This paper introduces an Algebraic MultiScale method for simulation of flow in heteroge-neous porous media with embedded discrete Fractures (F-AMS). First, multiscale coarse grids are independently constructed for both porous matrix and fracture networks. Then, amap between coarse-and fine-scale is obtained by algebraically computing basis...journal article 2016

Fragoso Rodrigues, S.M. (author), Bauer, P. (author), Bosman, P.A.N. (author)Currently, Offshore Wind Farms (OWFs) are designed to achieve high turbine density so as to reduce costs. However, due to wake interferences, densely packing turbines reduces energy production. Having insight into optimized trade-offs between energy production, capital investment and operational costs would be valuable to OWFs designers. To...journal article 2016

Wang, Y. (author), Hajibeygi, H. (author), Tchelepi, H.A. (author)The MultiScale Finite Volume (MSFV) method is known to produce non-monotone solutions. The causes of the non-monotone solutions are identified and connected to the local flux across the boundaries of primal coarse cells induced by the basis functions. We propose a monotone MSFV (m-MSFV) method based on a local stencil-fix that guarantees...journal article 2015
