Abstract:
This work focuses on high-rate () moderate-length () low-density parity-check codes. High-rate codes allow to maintain good quality of the preliminary decisions that are used in carrier recovery, while a moderate code length allows to keep the latency low. The interleaver of the LDPC matrix that we consider is inspired to the DVB-S2 standard one. A novel approach for avoiding short cycles is analyzed. A modified BP decoding algorithm is applied in order to deal with longer cycles. Simulations and results for the AWGN channel are presented, both for BPSK signalling and for coded modulation base

Abstract:
Conventional approach to perform error-correcting decoding in channels with memory is an adoption of interleaving, which increases the receiver complexity and delay. In order to avoid these limitations, approaches for adapting an error-correcting scheme for memory channels may be used. One approach is to use error-correcting codes with modified design and decoding procedure, taking into account the presence of error bursts in the channel. Another approach to adapting the coding scheme for burst error correction is to use product codes with iterative decoding algorithms. Component codes of prod

Abstract:
Use of an optical-rf relay deep space communication link is being considered1 that transmits optical MPPM data from a deep space vehicle to a satellite, then retransmits the data via microwave to ground. High-order (255,127) Reed-Solomon (RS) codes2 over the MPPM optical link for improved error correction have been considered. In this work we show that either timing errors or optical power constraint may cause severe degradation in system performance using high-order RS codes. Using an (8,4) extended Bose-:Chaudhuri-Hocquenhem (BCH) code as an inner code in a concatenated code in which the out

Abstract:
The present work studies the effect of entropy dispersion on the level of combustion noise at the turbine outlet of the Rolls-Royce ANTLE aero-engine. A new model for the decay of entropy waves, based on modelling dispersion effects, is developed and utilised in a low-order network model of the combustor (i.e. LOTAN code that solves the unsteady Euler equations). The proposed model for the dispersion of entropy waves only requires the mean velocity field as an input, obtained by RANS computations of the demonstrator combustor. LOTAN is then coupled with a low order model code (LINEARB) based o

Abstract:
The study of thermoacoustic combustion instabilities has an important role for safety operation in modern gas turbines equipped with lean premixed dry low emission combustion systems. Gas turbine manufacturers often adopt simulation tools based on low order models for predicting the phenomenon of humming. These simulation codes provide fast responses and good physical insight, but only one-dimensional or two-dimensional simplified schemes can be generally examined. The finite element method can overcome such limitations, because it allows to examine three-dimensional geometries and to search t

Abstract:
GPUs (Graphics Processing Units) are usually programmed using low-level languages like CUDA or OpenCL. Although these languages allow the implementation of very optimized software, they are difficult to program due to their low-level nature, where programmers have to mix coordination code, i.e., how tasks are created and distributed, with the actual computation code. In this paper we present Hok, an extension to the Elixir functional language that allows the implementation of higher-order GPU kernels, granting programmers the ability to clearly separate coordination from computation.

Abstract:
Low-fee private schools are today recognised as important players in the education market in developing countries, as they are argued to provide at least marginally better education than is on offer in the state schools. Leading international development agencies have begun encouraging governments in developing countries to include them within the policy-planning process. Based on fieldwork in two urban neighbourhoods in Pakistan, this paper shows that low-income parents are keen to secure good-quality education for their children, but they have to choose not only between state schools and low

Abstract:
This working paper discusses "Safer Commune" - a neighbourhood crime prevention program in Chile that has come under criticism via evidence of rising crime rates and fear of crime in municipalities with the program. The author argues that this criticism is incorrect and shows empirical evidence that the crime rates that would have been observed without the program. This impact evaluation -using the double difference propensity score method- reveals that the program has reduced high crimes particularly of two types of crimes namely battery and theft.

Abstract:
Dhaka has a population of about 19 million and many think it is a city of fortune. People come from all over the country to settle in Dhaka and many low-cost settlements (known as slums) have emerged since the country became independent. Findings of national survey reports suggest there is a high concentration of child labour in the slums of Dhaka, linked with the global supply chain of products. In order to understand the drivers of child labour in the slum areas of Dhaka, a research team formed of the Grambangla Unnayan Committee (GUC) with ChildHope UK designed and conducted a mapping and l

Abstract:
Although low-income parents’ dependence on low-fee private schools has been actively documented in the past decade, existing research and policy discussions have failed to recognise their heavy reliance on low-fee tuition providers in order to ensure that their children complete the primary cycle. By mapping a vibrant supply of low-fee tuition providers in two neighbourhoods in the twin cities of Rawalpindi and Islamabad in Pakistan, this paper argues for understanding the supply-side dynamics of this segment of the education market with the aim of designing better-informed policies, making be

They do so by looking at these companies’ publicly stated ambitions regarding diversification: they focus in particular on whether and how these companies are leaving fossil fuels behind, as a sign of transforming their core bus
