The benefits of growth for Indonesian Workers
No full textIndonesia's adopted development model has proved to be the most successful in alleviating poverty and benefiting workers in developing countries. The government's development efforts focused on agriculture, education, and transport infrastructure. It emphasized providing productive employment opportunities and gradually improving the labor quality through education and training. The wage, employment, and income growth rates were left to market forces. Although the rapid growth of labor-intensive manufacturing has led to more jobs and higher wages benefiting workers, workers employed in these industries have expressed growing dissatisfaction. They complain about problems of child labor, the denial of centrally mandated wages and benefits to workers, poor working conditions, and the abuse of young female workers. The government has tried to improve worker's wages and working conditions by centrally mandating higher labor standards, relying principally on minimum wages. Enforcement has improved and, despite low compliance, minimum wages are beginning to bite. Indonesians are debating whether they need labor intensive industries and whether it is a mistake to base Indonesia's growth on cheap labor. They argue that if labor is more expensive, manufacturers must substitute some capital for labor. However, if labor-intensive industries are rejected, the capacity of the economy to absorb plentiful workers will be reduced. The main alternatives are to push up wages now, or to let wages be determined by market forces and strengthen institutions that could improve working conditions, such as labor unions. The author recommends maintaining flexible labor markets and allowing market forces to set the pace of change, while strengthening labor unions.Environmental Economics&Policies,Public Health Promotion,Labor Policies,Health Monitoring&Evaluation,Work&Working Conditions,Environmental Economics&Policies,Health Monitoring&Evaluation,Banks&Banking Reform,Work&Working Conditions,Municipal Financial Management
Efficient inference of convolutional neural networks on general purpose hardware using weight repetition
No full textDeep Neural Networks (DNNs) have begun to permeate all corners of electronic society due to their high accuracy and machine efficiency per operation. Recent work has shown how weights within and across DNN filters have large degrees of repetition due to the pigeonhole principle and modern weight quantization schemes, and that this weight repetition can be harnessed improve DNN inference efficiency in an accelerator/ASIC context. This thesis develops new techniques so that weight repetition leads to an efficiency gain on general-purpose and programmable SIMD-based architectures such as CPUs equipped with vector extensions. We show how to write high-performance software that does not require hardware modifications and can cope with the irregularity introduced by weight repetition schemes. Overall, our highly parallel software kernel achieves up to 1:51 speedup in runtime of inference over state-of-the-art baseline.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2021-05-01The student, Rohit Agrawal, accepted the attached license on 2019-04-23 at 21:40.The student, Rohit Agrawal, submitted this Thesis for approval on 2019-04-23 at 21:43.This Thesis was approved for publication on 2019-04-24 at 15:53.DSpace SAF Submission Ingestion Package generated from Vireo submission #13851 on 2019-08-22 at 16:23:40Made available in DSpace on 2019-08-23T20:48:24Z (GMT).

ANOMALOUS TRANSPORT, QUASIPERIODICITY, AND MEASUREMENT INDUCED PHASE TRANSITIONS
No full textWith the advent of the noisy-intermediate scale quantum (NISQ) era quantum computers are increasingly becoming a reality of the near future. Though universal computation still seems daunting, a great part of the excitement is about using quantum simulators to solve fundamental problems in fields ranging from quantum gravity to quantum many-body systems. This so-called second quantum revolution rests on two pillars. First, the ability to have precise control over experimental degrees of freedom is crucial for the realization of NISQ devices. Significant progress in the control and manipulation of qubits, atoms, and ions, as well as their interactions, has not only allowed for emulation of diverse range of physical systems but has also led to realization of quantum systems in non-conventional settings such as systems out-of-equilibrium, driven by oscillating fields, and with quasiperiodic (QP) modulation. These systems often show novel properties which not only provide an interesting testbed for NISQ devices but also an opportunity to exploit them for further development of quantum computing devices. Second, the study of dynamics of quantum information in quantum systems is essential for understanding and designing better quantum computers. In addition to their practical application as resource for quantum computation, quantum information has also become an essential element for our understanding of various physical problems, such as thermalization of isolated quantum many-body systems. This interplay between quantum information and computation, and quantum many-body systems is only expected to increase with time. In this thesis, we explore these topics in two parts, corresponding respectively to the two pillars mentioned above. In the first part, we study effects of quasiperiodicity on many-body quantum systems in low dimensions. QP systems are aperiodic but deterministic, so their behavior differs from that of clean systems and disordered ones as well. Moreover, these systems can be conveniently realized in an experimental setting where it is easier to isolate them from external decoherence. %Recent advancement in experimental techniques has made it easier to design and probe quantum systems with quasi-periodic modulations. We start with the easy-plane regime of the XXZ spin chain and show that the well-known fractal behavior of the spin Drude weight implies the divergence of the low-frequency conductivity for generic values of anisotropy. We tie this to the quasi-periodic structure in the Bethe ansatz solution resulting in different species of quasiparticles getting activated along the time evolution in a quasi-periodic pattern. We then study quantum critical systems under generic quasi-periodic modulations using real-space renormalization group (RSRG) procedure. In 1d, we show that the system flows to a new fixed point with the couplings following a discrete aperiodic sequence which allows us to analytically calculate the critical properties. We dub these new classes of quasi-periodic fixed points infinite-quasiperiodicity fixed points in line with the infinite-randomness fixed point observed in random quantum systems. We use this approach to analyze the quasiperiodic Heisenberg, Ising, and Potts spin chains. The RSRG is not analytically tractable in 2d, but numerically implementing it for the 2d quasi-periodic -state quantum Potts model, we find that it is well controlled and becomes exact in the asymptotic limit. The critical behavior is shown to be largely independent of and is controlled by an infinite-quasiperiodicity fixed point. We also provide a heuristic argument for the correlation length exponent and the scaling of the energy gap. Moving on to the second part, we study monitored quantum circuits which have recently emerged as a powerful platform for exploring the dynamics of quantum information and errors in quantum systems. Unitary evolution generates entanglement between distant particles of the system. The dynamics of entanglement has been successfully studied by replacing the Hamiltonian evolution with random quantum circuits. Recently, the robustness of unitary evolution's ability to protect the entanglement against external projective measurements has received much attention. Entanglement is also a resource for quantum information, so its stability is directly related to the stability of a quantum computer against external noises. It has been observed that, in absence of any symmetry, there is a measurement induced phase transition (MIPT) in the behavior of bipartite entanglement that goes from volume law to area law as we tune the rate of measurements. Here we focus on monitored quantum circuits with U(1) symmetry which leads to the presence of a conserved charge density. These diffusive hydrodynamic modes scramble very differently than non-symmetric modes and we find that in addition to the entanglement transition, there is another transition \textit{inside} the volume phase which we call a ``charge sharpening'' transition. The sharpening transition is a transition in the ability/inability of the measurements to detect the global charge of the system. We study this sharpening transition in a variety of settings, including an effective field theory that predicts the transition to be in a modified Kosterlitz-Thouless universality class. We provide various numerical evidence to back our predictions.PhysicsDoctor of Philosophy (Ph.D.
