Title as it appears in MIT Commencement Exercises program, June 5, 2015: Improving throughput in the MGH Cancer Center Infusion Unit. Cataloged from PDF version of thesis.
Includes bibliographical references (pages 104-107).
This thesis proposes an appointment scheduling algorithm with associated supporting process changes that increases the effective capacity of the Massachusetts General Hospital Cancer Center Infusion Unit. Currently, chair and bed utilization in the Infusion Unit is concentrated between 10am-2pm, Monday through Friday, but remains underutilized during other operating hours. This uneven use of resources has resulted in highly strained staff and physical resources during rush hour, causing the perception of insufficient capacity. Moreover, when the environment is highly congested, patients experience long wait times and are more exposed to quality and safety problems. This study will recover unrealized capacity by smoothing the intra-day utilization of physical resources in the Infusion Unit. The scheduling algorithm is derived employing a retrospective integer program and validated using prospective simulation modeling. Implementation of these scheduling guidelines demonstrates the potential to recover 20 chairs, or 33% of capacity, at the average peak of each day, while smoothing throughput throughout the day. The proposed state can be achieved with minimal adjustments to staffing in the infusion unit and pharmacy, and no adjustment to staffing in the Oncology Practice. The algorithm also respects the existing primary nursing model, and treatment specific limitations.

In an effort to enable supply chain visibility for Intel products, the Customer Unit Level Traceability (ULT) Program was formed to help extend Intel's ULT capability to the customer level. Increased traceability of Intel products could potentially lead customers to realize some of the same benefits, such as improved issue management and security, as other industries already do. Interviewing customers regarding their perspectives on ULT and interest in pilot collaboration engagements with Intel allowed the program to realize that customer adoption would prove to be challenging. By characterizing the program with Everett M. Roger's Innovation Adoption Curve and Geoffrey A. Moore's Chasm, it was also discovered that the pragmatic early majority could not be expected to act as visionary innovators or early adopters and help the program reach a critical mass of customers with its existing strategy. However, the program may evolve to do so or at least reach its target customers by modifying the implementation plan. Rather than extending the ULT capability to customers as a risk mitigation strategy, Intel can effectively prepare a response for when inflection points occur and motivate customer ULT adoption. The timing of the adoption is largely sensitive to when customers are ready to bring on this sort of change and understanding what factors will cause this need. Ultimately, this project lends itself to the longer term, ideal state of having end-to-end traceability of Intel products along the supply chain whereby additional improvements in areas of quality and manufacturing can be discovered.

The mismatch channel capacity per unit cost represents the maximum number of bits per unit cost that can be transmitted reliably across a channel under receiver mismatch conditions. It's reciprocal is the minimal cost of transmitting a bit reliably under these conditions. We derive lower bounds for the mismatch channel capacity per unit cost and discuss some of its properties.

The goal of the "Fresh Breeze Project" is to develop a multi-core chip architecture that supports a better programming model for parallel computing. This architecture combines simultaneous multithreading, a global shared address space, no memory update, and a cycle-free heap to provide a platform for robust, general-purpose, parallel computation. These design choices help simplify classically hard problems such as memory coherency, control flow, and synchronization. An HDL implementation of the core execution unit of a single processing core (many cores are on a single chip) forms the basis of further simulation and synthesis. The design must first be broken down into functional logic blocks and translated into hardware modules. The language Bluespec Verilog allows this description to be constructed in terms of higher-level "guarded atomic actions" triggered by a rule based system.

The revenue of traditional auction mechanisms is benchmarked solely against the players' own valuations, despite the fact that they may also have valuable beliefs about each other's valuations. Not much is known about generating revenue in auctions of multiple identical copies of a same good. (In particular the celebrated Vickrey mechanism has no revenue guarantees.) For such auctions, we (1) put forward an attractive revenue benchmark, based on the players' possibilistic about each other, and (2) construct a mechanism that achieves such benchmark, assuming that thplayers are two-level rational (where the rationality is in the sense of Aumann).

Speech synthesis is an automatic encoding process carried out by machine through which symbols conveying linguistic information are converted into an acoustic waveform. In the past decade or so, a recent trend toward a non-parametric, corpus-based approach has focused on using real human speech as source material for producing novel natural-sounding speech. This work proposes a communication-theoretic formulation in which unit selection is a noisy channel through which an input sequence of symbols passes and an output sequence, possibly corrupted due to the coverage limits of the corpus, emerges. The penalty of approximation is quantified by substitution and concatenation costs which grade what unit contexts are interchangeable and where concatenations are not perceivable. These costs are semi-automatically derived from data and are found to agree with acoustic-phonetic knowledge. The implementation is based on a finite-state transducer (FST) representation that has been successfully used in speech and language processing applications including speech recognition. A proposed constraint kernel topology connects all units in the corpus with associated substitution and concatenation costs and enables an efficient Viterbi search that operates with low latency and scales to large corpora. An A* search can be applied in a second, rescoring pass to incorporate finer acoustic modelling. Extensions to this FST-based search include hierarchical and paralinguistic modelling. The search can also be used in an iterative feedback loop to record new utterances to enhance corpus coverage. This speech synthesis framework has been deployed across various domains and languages in many voices, a testament to its flexibility and rapid prototyping capability.
(cont.) Experimental subjects completing tasks in a given air travel planning scenario by interacting in real time with a spoken dialogue system over the telephone have found the system "easiest to understand" out of eight competing systems. In more detailed listening evaluations, subjective opinions garnered from human participants are found to be correlated with objective measures calculable by machine.

The story of Macbeth centers around revenge. World War I was started by an act of revenge. Even though these two stories are seemingly unrelated, humans use the same concept to draw meaning from them. Plot units, revenge included, are the common set of structures found in human narrative. They are the mistakes, the successes, the revenges and the Pyhrric victories. They are the basic building blocks of stories. In order to build a computational model of human intelligence, it is clear that we must understand how to process plot units. This thesis takes a step in that direction. It presents an English template for describing plot units and a system that is capable of turning these descriptions into plot-unit searches on stories. It currently processes 26 plot units, and finds 10 plot units spread out over Macbeth, Hamlet, the E-R Cyber Conflict, and a collection of legal case briefs.

Full textIncludes bibliographical references (p. 79-82).
In this thesis, an inertial measurement unit (IMU) consisting of 3 accelerometers and 3 rate gyros is created using off-the-shelf sensors from STMicro and Analog Devices. A novel technique for calibrating the orientation, position, scaling and offset of each of the sensors on the IMU is developed. A gimbal consisting of three concentric rings, with rotary encoders measuring the rotation between rings is designed. The IMU is fixed to the inner ring of the gimbal and rotated in space. By sweeping appropriate orientations of the IMU at appropriate rates, filtered sensor values can be mapped to "true" angular velocities and linear accelerations computed from the gimbal rotations. The sensor parameters are estimated via. MMSE, and a Kalman filter is implemented to estimate the IMU's attitude (roll and pitch angles) from the raw sensor values. The calibrated sensors are found to track the pitch angle with a mean-square-error of 1.7427 degrees, and the roll angle with a mean-square-error of 3.1387 degrees. The novel outcome of this thesis is that it defines a technique for calibrating IMUs with component sensors that need not be orthogonal in placement.

An ICU stay involves invasive treatments, and frequently, the decision to continue therapy is made with limited information based on the physician's personal experience. This thesis proposal describes a tool to assist this decision by identifying similar patients and using their outcomes for prediction. We used the eICU Collaborative Research Database (eICU-CRD) v2.0 for the project. Different time varying and time constant features about the patient's demographics and clinical trajectory was used as input data, such as patient age and longitudinal blood pressure measurement. Using this information, a Cox Proportional Hazards model was built to map the multivariate time series of input data to a univariate time series, which was used to match the patient to a cohort of similar patients. Based on the cohort, this model predicted the probability of a healthy discharge by using the aggregate outcome of the cohort for prediction.

Full textIncludes bibliographical references (p. 36).
This project focuses on characterizing intravenous (IV) medication administration in an intensive care unit at a partner hospital. Information regarding IV medication dose was extracted from MIMIC II, a large database containing real patient data; this information was used to characterize the use of twelve hemodynamic drugs. Characterization was performed by extracting features such as maximum dose and overall shape from each trend plot. Additionally, because the administration of vasoactive drugs is generally accompanied by a change in blood pressure, several methods were explored of representing patient state by combining the mean blood pressure and drug dose trends to gain more information than can be obtained by each trend alone. The results of drug use characterization show that an adequate picture of drug use can be gained by examining the characteristic shape of the dose trend in addition to features such as maximum dose administered. The patterns of medication administration have been shown to be indicative of overall patient state. The development of algorithms which match drug use trends to underlying physiology may aid in the annotation of large databases such as MIMIC II, and may also prove useful in tracking the hemodynamic state of a patient during his or her stay in intensive care.

Intensive care unit (ICU) patients undergo detailed monitoring so that copious information regarding their condition is available to support clinical decision-making. Full utilization of the data depends heavily on its quantity, quality and manner of presentation to the physician at the bedside of a patient. In this thesis, we implemented a visualization system to aid ICU clinicians in collecting, processing, and displaying available ICU data. Our goals for the system are: to be able to receive large quantities of patient data from various sources, to compute complex functions over the data that are able to quantify an ICU patient's condition, to plot the data using a clean and interactive interface, and to be capable of live plot updates upon receiving new data. We made significant headway toward our goals, and we succeeded in creating a highly adaptable visualization system that future developers and users will be able to customize.

Nano-electromechanical (NEM) relays are an alternative to CMOS transistors as the fabric of digital circuits. Circuits with NEM relays offer energy-efficiency benefits over CMOS since they have zero leakage power and are strategically designed to maintain throughput that is competitive with CMOS despite their slow actuation times. The floating-point unit (FPU) is the most complex arithmetic unit in a computational system. This thesis investigates if the energy-efficiency promise of NEM relays demonstrated before on smaller circuit blocks holds for complex computational structures such as the FPU. The energy, performance, and area trade-offs of FPU designs with NEM relays are examined and compared with that of state-of-the-art CMOS designs in an equivalent scaled process. Circuits that are critical path bottlenecks, including primarily the leading zero detector (LZD) and leading zero anticipator (LZA) blocks, are carefully identified and optimized for low latency and device count. We manage to drop the NEM relay FPU latency from 71 mechanical delays in a CMOS-style implementation to 16 mechanical delays in a NEM relay pass-logic style implementation. The FPU designed with NEM relays features 15x lower energy per operation compared to CMOS.

Because the vast majority of monitoring alarms in the adult intensive care unit (ICU) do not require intervention, care providers are slow to respond to all alarms, endangering patients. We collect, characterize, and analyze alarms, alarm annotations provided by clinical staff while responding to alarms, and physiological data from a community hospital ICU. In order to suggest opportunities for suppressing irrelevant alarms, we examine monitoring device coverage across patients and analyze the alarms observed by device, priority, and type. On average, we observe 196.3 alarms per patient-day, for a total of 23,057 alarms. From these, the electrocardiogram and pulse plethysmogram produce 86.1% of all alarms. The lowest priority alarms represent 81.1% of all alarms, while the highest priority alarms compose just 5.5% of the total. While the rate of annotations is low, also just 5.5% of possible alarms, it is comparable to the rate of care provider interactions with alarms, as measured by alarm silencing, at 9.6%. Using these annotations, we find -- surprisingly -- that the annotated nuisance threshold-violation alarms tend to have higher excursions than actionable and advisory alarms, offering a statistic for separation. When focusing on threshold-crossing alarms, we find that 22.5% of Heart Rate Low alarms may actually indicate device error. Among ST segment alarms, 44.4% occur simultaneously with at least one other ST segment alarm, producing redundant alarms. Addressing these issues represent strategies for reducing excessive alarms in this community hospital cohort of ICU patients.

Automated unit tests are essential for the construction of reliable software, but writing them can be tedious. If the goal of test generation is to create a lasting unit test suite (and not just to optimize execution of system tests), it is essential that generated tests can be understood by the developers that will be running them, so that they can tell the difference between real and spurious failures. amock is a system which automatically generates human-readable JUnit regression tests that use mock objects to simulate the behavior of individual objects dynamically observed during a system test execution.

Understanding changes in physiology in patients in the Intensive Care Unit (ICU) is important in determining care decisions. Machine learning algorithms have been used to model patient physiology to predict patient outcomes and administration of interventions. These predictions can be made directly on the raw patient data extracted from electronic health records. However, this data can be high dimensional with extraneous information. Neural networks, and in particular, autoencoders and sequence-to-sequence models, can be used to extract the important attributes of this time-series data without manual feature selection. In this work, we explore how learned encoded representations of physiological time-series and events time-series can be used to effectively predict outcomes on a variety of tasks. We compare the representations extracted from sequence-to-sequence models with representations extracted from autoencoders. We evaluate these representations on the task of predicting patient mortality and first onset of ventilator and vasopressor interventions. Our best representations achieve AUCs of 0.83, 0.91, and 0.91 on the tasks of mortality prediction, vasopressor first onset prediction, and ventilator first onset prediction, which is comparable to the performances using the raw features.

Full textThis thesis introduces a software framework that effectively utilizes low-cost commercially available Graphic Processing Units (GPUs) to simulate complex scientific plasma phenomena that are modeled using the Particle-In-Cell (PIC) paradigm. The software framework that was developed conforms to the Compute Unified Device Architecture (CUDA), a standard for general purpose graphic processing that was introduced by NVIDIA Corporation. This framework has been verified for correctness and applied to advance the state of understanding of the electromagnetic aspects of the development of the Aurora Borealis and Aurora Australis.
For each phase of the PIC methodology, this research has identified one or more methods to exploit the problem's natural parallelism and effectively map it for execution on the graphic processing unit and its host processor. The sources of overhead that can reduce the effectiveness of parallelization for each of these methods have also been identified. One of the novel aspects of this research was the utilization of particle sorting during the grid interpolation phase. The final representation resulted in simulations that executed about 38 times faster than simulations that were run on a single-core general-purpose processing system. The scalability of this framework to larger problem sizes and future generation systems has also been investigated.

The lack of effective data integration and knowledge representation in patient monitoring limits its utility to clinicians. Intelligent alarm algorithms that use artificial intelligence techniques have the potential to reduce false alarm rates and to improve data integration and knowledge representation. Crucial to the development of such algorithms is a well-annotated data set. In previous studies, clinical events were either unavailable or annotated without accurate time synchronization with physiological signals, generating uncertainties during both the development and evaluation of intelligent alarm algorithms. This research aims to help eliminate these uncertainties by designing a system that simultaneously collects physiological data and clinical annotations at the bedside, and to develop alarm algorithms in real time based on patient-specific data collected while using this system. In a standard pediatric intensive care unit, a working prototype of this system has helped collect a dataset of 196 hours of vital sign measurements at 1 Hz with 325 alarms generated by the bedside monitor and 2 instances of false negatives. About 89% of these alarms were clinically relevant true positives; 6% were true positives without clinical relevance; and 5% were false positives. Real-time machine learning showed improved performance over time and generated alarm algorithms that outperformed the previous generation of bedside monitors and came close in performance to the new generation. Results from this research suggest that the alarm algorithm(s) of the new patient monitoring systems have significantly improved sensitivity and specificity. They also demonstrated the feasibility of real-time learning at the bedside. Overall, they indicate
(cont.) that the methods developed in this research have the potential of helping provide patient-specific decision support for critical care.

Full textENGLISH ABSTRACT: This thesis investigates the possible use of NAND flash memory for a mass memory unit on a micro-satellite. The investigation begins with an analysis of NAND flash memory devices including the complexity of the internal circuitry and the occurrence of bad memory sections (bad blocks). Design specifications are produced and various design architectures are discussed and evaluated. Subsequently, a four bus serial access architecture using 16- bit NAND flash devices was chosen to be developed further. A VHDL design was created in order to realise the intended system functionality. The main functions of the design include a sustained write data rate of 24 MB/s, bad block management, multiple image storing, error checking and correction, defective device handling and reading while writing. The design was simulated extensively using NAND flash simulation models. Finally, a demonstration test board was designed and produced. This board includes an FPGA and an array of 16 8-bit NAND flash devices. The board was tested sucessfully and a write data rate of 12 MB/s was achieved along with all the other main functions.
AFRIKAANSE OPSOMMING: Hierdie tesis ondersoek die moontlike gebruik van NAND flash tegnologie as die geheue eenheid van ’n mikrosatelliet. As ’n beginpunt word NAND flash tegnologie ondersoek in terme van die kompleksiteit van interne stroombane en die voorkoms van defektiewe geheuesegmente. Daarna word ontwerpspesifikasies voortgebring en verskillende ontwerpsmoontlikhede met mekaar vergelyk. Vanuit hierdie oorwegings is daar besluit om die oplossing te implementeer met ’n vier-bus seri¨ele struktuur bestaande uit 16-bis NAND flash toestelle. Om die ontwerpspesifikasies te realiseer, is ’n VHDL stelsel geskep. Die belangrikste funksies van hierdie stelsel is ’n konstante skryftempo van 24 MB/s, die bestuur van defektiewe geheuesegmente, die stoor van meer as een beeld, foutopsporing en -herstel, optimale werking in die geval van defektiewe geheuetoestelle en laastens, die gelyktydige lees en skryf van data. Die stelsel is breedvoerig getoets met NAND flash simulasiemodelle. Ten slotte is ’n fisiese demonstrasiebord, bestaande uit ’n FPGA en 16 8-bis NAND flash toestelle, ontwerp en gebou. Fisiese metings was ’n sukses. ’n Skryftempo van 12 MB/s is gehaal, tesame met die korrekte werking van die ander hooffunksies.

As technology and society become further intertwined, it is imperative that we democratize the creation of technology and educate people to be capable of harnessing the full power of computational thinking. As such, developing meaningful tools and curricula for incremental learning of computational thinking concepts starting in primary education is an important endeavor [1]. My work focuses on making Cloud technology, one of the most powerful new computer science concepts, understandable and usable by anyone without the need for extensive computer science training. I used MIT App Inventor, a blocks-based mobile application development tool for teaching computational thinking to young students, as the platform for my research. I developed CloudDB, a set of coding blocks for MIT App Inventor that allows users to store, retrieve, and share various types of data in tag-value pairs on a Redis server for their mobile applications. I created middle and high school level curricula based on CloudDB along with assessment tools to evaluate my materials and the extent to which young students can understand and utilize the concepts around shared data. Finally, I ran one of those workshops with middle school students in the MIT area. My findings indicate that teaching shared data as a core computational thinking concept is entirely feasible to students as young as middle school level. Students are capable of inferring and extrapolating other use cases and potential problems with the Cloud, such as storage limits and security concerns. When given the context of solving a problem in their lives, they are very driven and able to design and create complex independent mobile application projects using MIT App Inventor and CloudDB.

Companies currently utilize a number of different approaches to making decisions around where to locate factories. This thesis analyzes the specific challenges faced by Polaroid Corporation in making site location decisions for its instant film assembly operation. The methodology used to arrive at this specific set of recommendations, however, can be extended for use by any company. Three main approaches are taken for determining the optimal site locations: The first approach involves the development of a simplified cost model. This exposes the current cost competitiveness of the sites under consideration. The sites are also evaluated under a variety of scenarios to determine their performance under future variance in exchange rates. The second analytical method employed is a characteristic matrix. This approach facilitates the inclusion of qualitative factors which may be critical to the performance of the factory. All four of Polaroid's film assembly factories were visited to observe the unique capabilities of the sites. A graphical representation of the sites' proficiency for development activities, low cost manufacturing, and flexible manufacturing is developed. In the final technique, the strategic trends and decisions of the instant film business are examined. The company is in the midst of a radical shift in product strategy. New products are being positioned on the basis of fashion more than performance. This shift has important implications for the demands placed on the manufacturing organization. An integrated set of recommendations is synthesized from the results of the three separate approaches. A shift in plant focus from product and market focus to life cycle focus is suggested. The sites with the capabilities and cost structure for the different life cycle roles are identified.
