Diagrams are an essential means of capturing and communicating information in many different domains. They are also a valuable part of the early design process, helping us explore ideas and solutions in an informal environment. This paper presents a new approach to sketched symbol recognition that preserves as much of the visual nature of the symbol as possible. Our method is robust to differen...

This paper addresses two problems that arise when analyzing executables: (1) recovering variable-like quantities in the absence of symbol-table and debugging information, and (2) recovering useful information about objects allocated in the heap.

In this paper we present an analytical approach to evaluate the M-QAM symbol error rate (SER) of Alamouti space time coded OFDM direct conversion receivers subject to carrier frequency offset (CFO), channel estimation errors, outdated channel state information, limited ADC resolution and flat receiver I/Q imbalance in Rayleigh time and frequency selective fading channels. The SER is numerically...

We propose a novel framework for improving a word segmenter using information acquired from symbol grounding. We generate a term dictionary in three steps: generating a pseudo-stochastically segmented corpus, building a symbol grounding model to enumerate word candidates, and filtering them according to the grounding scores. We applied our method to game records of Japanese chess with commentar...

12. Considering discrete-time channels, sketch a chart showing the following plots: (a) Continuous-valued AWGN channel capacity (bits/symbol) as a function of SNR (b) Maximal conveyed information as a function of SNR for the following alphabets: 2-PSK, 4-PSK, 16-QAM, 64-QAM The characteristic shapes of the curves and asymptotic behaviors are essential. 13. The capacity per symbol for a continuo...

We present simple coding strategies, which are variants of the Schalkwijk-Kailath scheme, for communicating reliably over additive white noise channels in the presence of corrupted feedback. More specifically, we consider a framework comprising an additive white forward channel and a backward link which is used for feedback. We consider two types of corruption mechanisms in the backward link. T...

Code generation is regarded as an essential part of model-driven development (MDD) to systematically transform the abstract models to concrete code. One current challenges of templatebased code generation is that output-specific information, i.e., information about the generated source code, is not explicitly modeled and, thus, not accessible during code generation. Existing approaches try to e...
