Enabling aggressive compiler optimization for the mobile environment
Creators: name: Mpeis, Paschalis

description: Aggressive code optimization on the mobile environment is a difficult endeavor. Billions of users rely on mobile devices for their daily computing tasks. Yet, they mostly run poorly optimized code, under-utilizing their already limited processing and energy resources. Existing optimization approaches, like iterative compilation, perform well in other domains but fall short on the mobile environment. They either rely on representative inputs that are hard to reconstruct, or expose users to slowdowns and crashes. An ideal solution must be able to perform an optimization search by repeatedly evaluating different optimization decisions on the same input. That input should be representative of actual user usage without requiring developers to artificially create it. Finally, users should never be exposed to slow or crashing evaluations, a quite common side-effect of iterative compilation. This thesis presents a novel approach with all above in mind, bringing aggressive code optimization to the mobile environment. With a transparent capture mechanism, real user inputs can be stored. This mechanism is infrequently invoked and remains unnoticeable from the users. A single capture is enough to enable offline, input-driven code optimization. It supports C functions as well as code regions of interactive Android applications. It allows controlling the timing and frequency of captures, it bails out on imminent high-impact runtime events, and excludes from captures some immutable data. A replay-based evaluation mechanism is able to repeatedly restore a captured input while changing the underlying code. For C programs, it employs compile and link-time strategies to consistently work despite code transformations. For Android apps, a novel mechanism was developed, able to replay using different code types. These are the original Android-compiled code, interpretation, and LLVM-generated code. Additionally, it works well even in the presence of memory-shuffling security mechanisms. Capture and replay is fused into an iterative compilation system that uses offline, replay-based evaluations. Initially, real inputs are captured online, without noticeably affecting the users. For C and interactive apps, captures required on average 2ms and 15ms respectively. Then, an optimization search is performed by repeatedly replaying the inputs using different code transformations. As this happens offline, any crashing or erroneous executions are not affecting the users. C programs became 29% faster using a random search, while interactive apps became 44% faster using a genetic algorithm and a novel Android backend based on LLVM. Finally, with crowd-sourcing, the offline evaluation effort was significantly accelerated. Specifically, for the user with the highest workload the search accelerated by 7 times.

description: Urban flooding crisis in Bangkok plays an important role in the lives of people. Sponge City is a concept to alleviate the problem. The paper aims to estimate the willingness to pay of people in Bangkok to initiate a Sponge City project. According to a study of 300 respondents by the Contingent Valuation Method (CVM). The results show that the average of willingness to pay for Sponge city per person is 145 – 158 baht. Furthermore, the factors that contributed to the willingness to pay for the project were the initial bid and the opinion on the future flooding problem. The results indicate that the socio-economic characteristics including anxiety is important in carrying out activities for people to participate. Therefore, to enhance people participation in the Sponge city, the project should start during the period of economic expansion or launch in the areas with high demand or good economic zones. As well, policy makers should promote the project through various channels and should promote to make people aware of the problem.---ปัญหาน้าท่วมในกรุงเทพมหานครมีบทบาทสาคัญในการดาเนินชีวิตของคนในสังคม การก่อสร้างเมืองฟองน้าจึงเป็นแนวคิดเพื่อบรรเทาผลกระทบที่อาจจะเกิดได้ ซึ่งประชาชนในพื้นที่จะมีส่วนในการได้รับประโยชน์โดยตรง บทความนี้มีวัตถุประสงค์เพื่อวิเคราะห์การรับรู้และความเต็มใจจ่ายของประชาชนในกรุงเทพมหานครต่อการริเริ่มโครงการเมืองฟองน้า โดยผลการศึกษาจากกลุ่มตัวอย่าง 300 ราย ด้วยวิธีสมมติเหตุการณ์ให้ประเมินค่า (Contingent Valuation Method: CVM) พบว่าค่าเฉลี่ยของความเต็มใจที่จะจ่ายเงินบริจาคในการดาเนินโครงการเมืองฟองน้าต่อรายอยู่ที่ 145 – 158 บาท โดยปัจจัยที่ส่งผลต่อความเต็มใจจ่ายเพื่อให้เกิดโครงการ คือ ราคาที่นาเสนอเริ่มต้น และความกังวลต่อเหตุการณ์น้าท่วมในอนาคต ผลการวิจัยชี้ให้เห็นว่าลักษณะทางเศรษฐกิจและสังคม รวมถึงความวิตกกังวลมีความสาคัญในการดาเนินกิจกรรม เพื่อให้ประชาชนมีส่วนร่วม ภาครัฐหรือหน่วยงานที่เกี่ยวข้องควรเริ่มจากการวางแนวนโยบายในการทาโครงการในช่วงที่มีการขยายตัวทางด้านเศรษฐกิจ หรือเริ่มต้นในพื้นที่ที่มีลักษณะของเศรษฐกิจที่ดี ตลอดจนการประชาสัมพันธ์โครงการผ่านช่องทางต่างๆ ควรให้มีการแทรกเนื้อหาในเชิงผลกระทบที่สาคัญ เพื่อให้ประชาชนเกิดความตระหนักต่อปัญหา อันจะส่งผลต่อความเชื่อมั่นในโครงการที่จะเกิดขึ้นในอนาคต

description: Thailand’s rice has set a supreme quality standard in the world market. Seed is one of the important factors contributing to good quality grains. As the competition for quality rice in the world market is becoming intensive, rice seeds play a significant role not only to ensure food and income security but also to retain quality and competitiveness of Thai rice in the world market. This paper reviews policies and regulations related to rice seed industry in Thailand, current situations of rice seed system, the supply and demand of rice seeds, and implications for future rice seed industry development. It is found that some of current regulations and business environment do not create much incentive for investments for the private sector. The imports and exports of rice seeds are practically prohibited. Thus, most of existing rice seeds in the market comprise of mainly public varieties produced by formal seed sector with a few exceptions of privately developed varieties by Thai companies, farmers’ groups and research institutes. None of the foreign stakeholders is in rice seed industry in Thailand presently. As seed producers do not hold exclusive rights to reproduce public varieties, and because all of the varieties are not hybrids, informal seed system is the major source of rice seeds. The systems of rice seed suggest that formal and informal systems can be integrated and linkages between both systems should create incentives for business opportunities.

description: Thin gap chambers (TGCs) are built for the muon trigger chambers in the endcap region of the LHC experiment ATLAS. More than 2500 ATLAS TGCs are being produced at the Weizmann institute in Israel, and in Shandong University in China. Detailed testing of these chambers is performed at the Technion and at the Tel-Aviv University. Two cosmic ray hodoscopes for testing the operation of these detectors were built in Israel. In these hodoscopes the response of the chambers to energetic cosmic ray muons is recorded and analyzed. The hodoscopes measure the exact time and space location of the cosmic ray hit and read out the chambers which are being tested to verify that they produce a corresponding signal within the required time interval. The cosmic ray hodoscopes built at the Technion and at the Tel Aviv University for the test of ATLAS TGCs are described. The mechanical structure, readout electronics, data acquisition and operating scheme are presented. Typical TGC test results are presented and discussed.

description: We theoretically study the optomechanically induced transparency (OMIT) and absorption(OMIA) phenomena in a single microcavity optomechanical system, assisted by an indirectly-coupledauxiliary cavity mode. We show that the interference effect between the two optical modes playsan important role and can be used to control the multiple-pathway induced destructive or construc-tive interference effect. The three-pathway interference could induce an absorption dip within thetransparent window in the red sideband driving regime, while we can switch back and forth betweenOMIT and OMIA with the four-pathway interference. The conversion between the transparencypeak and absorption dip can be achieved by tuning the relative amplitude and phase of the multiplelight paths interference. Our system proposes a new platform to realize multiple pathways inducedtransparency and absorption in a single microcavity and a feasible way for realizing all-opticalinformation processing.

Classical basis for quantum spectral fluctuations in hyperbolic systems

description: We reason in support of the universality of quantum spectral fluctuations in chaotic systems, starting from the pioneering work of Sieber and Richter who expressed the spectral form factor in terms of pairs of periodic orbits with self-crossings and avoided crossings. Dropping the restriction to uniformly hyperbolic dynamics, we show that for general hyperbolic two-freedom systems with time-reversal invariance the spectral form factor is faithful to random-matrix theory, up to quadratic order in time. We relate the action difference within the contributing pairs of orbits to properties of stable and unstable manifolds. In studying the effects of conjugate points, we show that almost self-retracing orbit loops do not contribute to the form factor. Our findings are substantiated by numerical evidence for the concrete example of two billiard systems.

description: We present a simple and effective multigrid-based Poisson solver of second-order accuracy in both gravitational potential and forces in terms of the one, two and infinity norms. The method is especially suitable for numerical simulations using nested mesh refinement. The Poisson equation is solved from coarse to fine levels using a one-way interface scheme. We introduce anti-symmetrically linear interpolation for evaluating the boundary conditions across the multigrid hierarchy. The spurious forces commonly observed at the interfaces between refinement levels are effectively suppressed. We validate the method using two- and three-dimensional density-force pairs that are sufficiently smooth for probing the order of accuracy.

Mapping the dark matter using weak lensing

description: Weak gravitational lensing of distant galaxies by foreground structures has proven to be a powerful tool to study the mass distribution in the universe. The advent of panoramic cameras on 4m class telescope has led to a first generation of surveys that already compete with large redshift surveys in terms of the accuracy with which cosmological parameters can be determined. The next surveys, which already have started taking data, will provide another major step forward. At the current level, systematics appear under control, and it is expected that weak lensing will develop into a key tool in the era of precision cosmology, provided we improve our knowledge of the non-linear matter power spectrum and the source redshift distribution. In this review we will briefly describe the principles of weak lensing and discuss the results of recent cosmic shear surveys. We show how the combination of weak lensing and cosmic microwave background measurements can provide tight constraints on cosmological parameters. We also demonstrate the usefulness of weak lensing in studies of the relation between the galaxy distribution and the underlying dark matter distribution (``galaxy biasing''), which can provide important constraints on models of galaxy formation. Finally, we discuss new and upcoming large cosmic shear surveys.

description: Agricultural development policy in Thailand over the past few decades has been geared not only to the nation’s food security, but also to export earnings. Thailand is a food surplus country at the macro level but food accessibility at the household level remains a problem, particularly in remote rural areas. The recent increase in food price and production cost has impacted on the rural poor. With a declining purchasing power, the poor households face the risk of food insecurity as they may reduce their intake of more nutritious food. The impact of rising food prices on agricultural households depends on whether they are net buyers of food commodities whose prices have increased. In rice farming households, the share of net buyer households was higher among households with smaller land holding. Also, the poor rice farmers in Thailand were severely affected by the higher production cost and input prices since the reduction in their net profits was larger. While nearly two-thirds of their operating cost was cash expense, they received only one-tenth from the rice sold. In order for the rural poor to cope with future impacts of high food price and rising production cost, a provision of off-farm employment and micro-credit with technical assistance and proper farm management plans should be targeted to small farmers and rural poor. In the longer-run, it is suggested that small-scale farmer capacity building and empowerment based on the sufficiency economy concept is necessary. This should be complemented by enhancing farm productivity through agricultural research and improvement in village-pool water resources including on-farm water resource management and investment.

description: Dietary restriction (DR) is the most successful and widespread means of extending organismal lifespan. However, the evolutionary basis of life extension under DR remains uncertain. The traditional evolutionary explanation is that when organisms experience DR, they allocate endogenous resources to survival and postpone reproduction until conditions improve. However, this life-extension strategy should be maladaptive if DR continues for multiple generations due to trade offs between longevity and reproduction. To test this prediction, we subjected the budding yeast Saccharomyces cerevisiae to 1800 generations of evolution on restricted versus non-restricted diets. Adaptation to a non-restricted diet improved reproductive fitness by 57%, but provided a much smaller (14%) advantage on a restricted diet. By contrast, adaptation to DR resulted in an approximately 35% increase in reproductive fitness on both restricted and non-restricted diets. Importantly, the life-extending effect of DR did not decrease following long-term evolution on the restricted diet. Thus, contrary to theoretical expectations, we found no evidence that the life-extending DR response became maladaptive during multigenerational DR. Together, our results suggest that the DR response has a low cost and that this phenomenon may have evolved as part of a generalist strategy that extends beyond the benefits of postponing reproduction.
Effects of immersed moonlets in the ring arc particles of Saturn

description: Ring arcs are the result of particles in corotation resonances with nearby satellites. Arcs are present in Saturn and Neptune systems, in Saturn they are also associated with small satellites immersed on them. The satellite Aegaeon is immersed in the G~ring arc, and the satellites Anthe and Methone are embedded in arcs named after them. Since most of the population of the arcs is formed by $μ$m-sized particles the dissipative effects, such as the plasma drag and the solar radiation force, decrease the lifetime of the arcs. We analysed the effects of the immersed satellites on these arcs by computing the mass production rate and the perturbation caused by them in the arc particles. By comparing the lifetime of the particles and the mass production rate we concluded that Aegaeon, Anthe and Methone did not act as sources for their arcs. We took a step further by analysing a hypothetical scenario formed by an immersed moonlet of different sizes. As a result we found that regardless the size of the hypothetical moonlet (from about 0.10 km to 4.0 km) these moonlets will not act as a source. These arcs are temporary structures and they will disappear in a very short period of time.

Spectral form factor of hyperbolic systems: leading off-diagonal approximation

Publisher: name: arXiv
Year: 2003
Subjects: subject: Chaotic Dynamics (nlin.CD)
subject: FOS: Physical sciences

description: The spectral fluctuations of a quantum Hamiltonian system with time-reversal symmetry are studied in the semiclassical limit by using periodic-orbit theory. It is found that, if long periodic orbits are hyperbolic and uniformly distributed in phase space, the spectral form factor agrees with the GOE prediction of random-matrix theory up to second order included in the time measured in units of the Heisenberg time (leading off-diagonal approximation). Our approach is based on the mechanism of periodic-orbit correlations discovered recently by Sieber and Richter (Phys. Scr. T 90, 128, 2001). By reformulating the theory of these authors in phase space, their result on the free motion on a Riemann surface with constant negative curvature is extended to general Hamiltonian hyperbolic systems with two degrees of freedom.

description: This paper studies total factor productivity (TFP) in Thai agriculture to provide better empirical evidence on the TFP measure and the factors influencing it. It employs time-series data at an aggregate level over the period 1970-2006 for both crops and livestock, individually, using the conventional growth accounting framework. The TFP measures are then used to investigate their determinants using the error correction modeling technique. The results confirm the general expectation from previous studies that TFP makes an important contribution to output growth and that agricultural research plays an important role in determining TFP in both the crop and livestock sectors.

Microscopic Theory of the Influence of Strong Attractive Forces on the Activated Dynamics of Dense Glass and Gel Forming Fluids

description: We theoretically study the non-monotonic (re-entrant) activated dynamics associated with a repulsive glass to fluid to attractive glass transition in high density particle suspensions interacting via strong short range attractive forces. The classic theoretical projection approximation that replaces all microscopic forces by a single effective force determined solely by equilibrium pair correlations is revisited based on the projectionless dynamic theory (PDT) that avoids force projection. A hybrid-PDT is formulated that explicitly quantifies how attractive forces induce dynamical constraints, while singular hard core interactions are treated based on the projection approach. Both the effects of interference between repulsive and attractive forces, and structural changes due to attraction-induced bond formation that competes with caging, are included. Combined with the microscopic Elastically Collective Nonlinear Langevin Equation (ECNLE) theory of activated relaxation, the resultant approach appears to properly capture both the re-entrant dynamic crossover behavior and the strong non-monotonic variation of the activated structural relaxation time with attraction strength and range at very high volume fractions. Qualitative differences with ECNLE theory-based results that adopt the full projection approximation are identified, and testable predictions made. The new formulation appears qualitatively consistent with multiple experimental and simulation studies, and provides a new perspective for the overall problem that is rooted in activated motion and interference between repulsive and attractive forces. This is conceptually distinct from empirical shifting or other ad hoc modifications of ideal mode coupling theory which do not take into account activated dynamics. Implications for thermal glass forming liquids are briefly discussed.

We performed a panel analysis of the rolling window method for all combinations of approach to criticality start months from July 1981 through May 1982 and supercritical start months from November 1992 through September 1993.

description: The students of PLAN 587B Introductory Urban Design Studio, under the instruction of Dr. Maged Senbel, worked in collaboration with developer Wayne Allen to create 3 sustainable designs for the redevelopment of an amalgamated site in the Big Bend area of Burnaby BC adjacent to Willard Park. Concurrently, through a research-based directed study project Jeca Glor-Bell conducted research on green design principles and technologies to aid the design students in achieving a high level of sustainability in design. This book brings together the research on green design principles and application of green technologies with the final designs. The purpose of this effort is to offer a resource for the developer, other urban planning students as well as interested practitioners seeking to apply green design principles and technologies to future sites. The book begins by explaining the green principles and features which have informed and influenced these designs and then presents the three completed site designs. The first site design, Fenwick Village, was created by Jennifer Fix, Bronwyn Jarvis and Chani Joseph. The second design, Willard’s Eco-Village, was created by Brian Gregg, Lang Lang and Sawngjai Manityakul, and finally the Sprout: The City is the Country Design which was created by Kaitlin Kazmierowski, Jeff Deby and Andrew Merrill. Each of these designs sought to combine three elements: the client’s vision, ecological development principles, and green design features. Finally the book includes several appendices with greater detail on the application of green energy technologies, including calculations for the capacity of different green technologies.

description: The blue compact dwarf galaxy NGC 5253 hosts a very young central starburst. The center contains intense radio thermal emission from a massive ultracompact H II region (or "supernebula") and two massive and very young super star clusters (SSCs), which are seen at optical and infrared wavelengths. The spatial correspondence between these three objects over an area of < 0.5 arcsec is very uncertain, and it is usually assumed that one of the optically-detected SSCs coincides with the supernebula. Using the Gaia Data Release 2 catalog, we improve the absolute astrometry of Hubble Space Telescope ultraviolet, optical and infrared images by a factor of ~10 and match them to the radio observations with an accuracy of 10-20 mas. We find that there are 3 SSCs at the center of NGC 5253. At optical wavelengths, the two SSCs lie either side of the supernebula, which coincides with a highly obscured region. In the infrared, all 3 SSCs are seen with the supernebula dominating at the longest wavelengths. We examine the properties of the SSCs, which have ages of ~ 1 Myr, are very compact (<0.6 pc) and separated by projected distances of only 1.5 and 5.8 pc. It seems likely that they will merge and may form the building blocks for nuclear star clusters.

description: China, Thailand, and Vietnam are key players in world rice market in terms of production and trade. In the past few decades, rice policies in these three countries have changed significantly resulted in changes in production, exports and influences in the world market. This paper reviews major rice policy reforms in China, Thailand and Vietnam during past five decades. It is observed that although each country has practiced different policies at different periods, with the economic development, individuals and market forces have played more important roles in domestic market while government interventions still exist and it is important for the government to invest in rice breeding technology and infrastructure construction. It was found that China and Vietnam have benefited from farm system reforms, the adoption of hybrid rice and the investment in irrigation while liberalization of rice export premium and provision of credits in 1980s have helped Thailand to become the largest rice exporter.

description: This article aims at introducing a spatial aspect of analyzing the relationship between economic growth and poverty, in which the geographical disparity plays an important role. A case study of growth poverty elasticity of Sumatra, Indonesia, using district-level data, is provided as an example of how spatial issues can be incorporated in the analysis. An application of spatial regression is introduced as a suitable method. The case study of Sumatra indicates that spatial influence exists in the poverty determinant model and this spatial relationship shall not be ignored in estimating GEP. Poverty incidence in Sumatra tends to be concentrated in particular locations which is influenced by spatial factors such as types of land, soil condition, transportation, and infrastructure. This suggests a poverty alleviation program should be developed targeting larger regional bases, rather than concentrating on various small areas. This method can be applied in a number of topics in agricultural economics as well as other fields relating to location factors and neighborhood influence.

description: In this paper we analyze the effects of institutional variables (corruption and governance), structural variables (per capita income, trade openness, inflation and share of agriculture in GDP), and policy variables (tax rate and tariff rate) on total tax revenues, direct taxes, indirect taxes and trade taxes using panel data set for 30 African countries over the 1996-2016 period. All estimates are based on fixed effects (FE) and random effects (RE) models. Using Hausman test, RE is earmarked to be the more preferred model in this paper. The RE regression results show that corruption and governance are two main determinants of tax revenues in Africa. While corruption has a significant negative effect on tax revenues, good governance measured in terms of government effectiveness, regulatory quality, rule of law and voice and accountability tends to raise tax revenue generation and in particular, indirect taxes. In the same vein, governance in form of political stability tends to have a very significant effect on direct taxes and international trade taxes. The basic intuition behind these results is that higher institutional capacity and lower corruption enhance tax revenue generation in the economy. Intriguingly, empirical results show that tariff rates tend to have a strong negative effect on total tax revenue but at the same time they have a strong positive effect on trade tax revenue. Moreover, trade openness tends to have a strong positive relationship with tax revenue. Overall, results suggest that to raise more tax revenue, governments should reduce corruption, improve tax and customs administration and raise revenues from tax categories that are less susceptible to corruption. They should as well enhance trade openness.
Efficient Production of S$_8$ in Interstellar Ices: The effects of cosmic ray-driven radiation chemistry and non-diffusive bulk reactions

description: In this work, we reexamine sulfur chemistry occurring on and in the ice mantles of interstellar dust grains, and report the effects of two new modifications to standard astrochemical models; namely, (a) the incorporation of cosmic ray-driven radiation chemistry and (b) the assumption of fast, non-diffusive reactions for key radicals in the bulk. Results from our models of dense molecular clouds show that these changes can have a profound influence on the abundances of sulfur-bearing species in ice mantles, including a reduction in the abundance of solid-phase H$_2$S and HS, and a significant increase in the abundances of OCS, SO$_2$, as well as pure allotropes of sulfur, especially S$_8$. These pure-sulfur species - though nearly impossible to observe directly - have long been speculated to be potential sulfur reservoirs and our results represent possibly the most accurate estimates yet of their abundances in the dense ISM. Moreover, the results of these updated models are found to be in good agreement with available observational data. Finally, we examine the implications of our findings with regard to the as-yet-unknown sulfur reservoir thought to exist in dense interstellar environments.

description: The concepts of Riesz type and cotype of a given Banach space are extended to a non-commutative setting. First, the Banach space is replaced by an operator space. The notion of quantized orthonormal system, which plays the role of the orthonormal system in the classical setting, is then defined. The Fourier type and cotype of an operator space with respect to a non-commutative compact group fit in this context. Also, the quantized analogs of Rademacher and Gaussian systems are treated. All this is used to obtain an operator space version of the classical theorem of Kwapień characterizing Hilbert spaces by means of vector-valued orthogonal series. Several approaches to this result with different consequences are given.

description: We compare the standard single scalar field inflationary predictions with those of an inflationary phase driven by a tachyon field. A slow-roll formalism is defined for tachyon inflation and we derive the spectra of scalar and tensor perturbations as well as the consistency relations. At lowest order the predictions of standard and tachyon inflation are the same. Higher order deviations are present and their observational relevance is discussed. We discuss the observational consequences of some typical inflationary tachyon potentials and compare them with recent data. All the models predict a negative and very small running of the scalar spectral index, and they consistently lie within the 1$σ$ contour of the data set. However, the regime of blue scalar spectral index and large gravity waves is not explored by these models.
