Identifying New Customers Using Machine Learning

In this thesis, we examine machine learning as a tool for predicting new customers in a B2B-sales context. Using only publicly available information, we try to solve the problem using two different approaches: 1) a naive clustering based classifier built on K-means and 2) PU-learning with a random forestsadapter. We test these models with different sets of features and evaluate them using statistical measures and a discussion of the business implications. Our main findings conclude that the PU-learning could produce results that are satisfactorily for the purpose of improving the sales process, with the best case of being 4.8 times better than a random baseline classifier. However, the clustering based classifier was not good enough, producing only marginally better results than a random classifier in its best case. We also find that using more variables improved the models, even in high-dimensional spaces with over 60 variables. Acknowledgements This thesis was written in collaboration with Exsitec AB.

CASH HOLDINGS IN BRAZIL: A STUDY CONSIDERING THE EFFECTS OF FINANCIAL CONSTRAINTS AND THE ADOPTION OF INTERNATIONAL FINANCIAL REPORTING STANDARDS

Firms use of internal and external sources to finance their activities. However, in the presence of imperfections in capital market, such as information asymmetry, agency problems and transaction costs, they may opt for one over another. In this sense, evidence obtained from previous studies suggests that cash holdings are more valuable for restricted companies than for unrestricted ones. Furthermore, the IFRS adoption is one of the most important subjects in recent accounting history. We analyze, in this article, the effects of financial constraints and the IFRS adoption on cash management in Brazil. For that, we used the Generalized Method of Moments (GMM) by dynamic panel data in order to explicitly consider the problems of endogeneity. The sample used comprises 219 public firms from 2000 to 2017. Our results indicate that, on average, the cash management of firms is influenced by its level of financial constraint. Financially constrained firms by size criteria and dividend-paying hold more cash than the smaller ones and non-dividend paying firms, respectively. We also verify a significant reduction in cash levels after the mandatory adoption of IFRS. Finally, our results reveal that firms’ leverage, profitability, growth opportunities, current liquidity, net working capital and short-term debt are important in determining cash holdings in Brazil.
An Autonomous Biped - Concept and Design

This paper argues for a new approach in the mechanical design principle for the humanoid walkers. Applying linear electric direct drive motors the biped mechanism is able to behave as dynamically highly reactive walker admissible to exploiting its own natural dynamics. Based on this, a whole new concept of an anthropomorphic walker prototype is described including the interaction of the design and algorithmic aspects of the motion control.
A SYSTEMATIC STUDY OF MID-INFRARED EMISSION FROM CORE-COLLAPSE SUPERNOVAE WITH SPIRITS

We present a systematic study of mid-infrared emission from 141 nearby supernovae (SNe) observed with Spitzer/IRAC as part of the ongoing SPIRITS survey. We detect 8 Type Ia and 36 core-collapse SNe. All Type Ia/Ibc SNe become undetectable within three years of explosion, whereas 22 ± 11% of Type II SNe continue to be detected. Five Type II SNe are detected even two decades after discovery (SN 1974E, 1979C, 1980K, 1986J, and 1993J). Warm dust luminosity, temperature, and a lower limit on mass are obtained by fitting the two IRAC bands, assuming an optically thin dust shell. We derive warm dust masses between 10−6 and 10−2 M⊙ and dust color temperatures between 200 and 1280 K. This observed warm dust could be pre-existing or newly created, but in either case represents a lower limit to the dust mass because cooler dust may be present. We present three case studies of extreme SNe. SN 2011ja (II-P) was over-luminous ([4.5] = −15.6 mag) at 900 days post explosion with increasing hot dust mass, suggesting either an episode of dust formation or intensifying circumstellar material (CSM) interactions heating up pre-existing dust. SN 2014bi (II-P) showed a factor of 10 decrease in dust mass over one month, suggesting either dust destruction or reduced dust heating. The IR luminosity of SN 2014C (Ib) stayed constant over 800 days, possibly due to strong CSM interaction with an H-rich shell, which is rare among stripped-envelope SNe. The observations suggest that this CSM shell originated from an LBV-like eruption roughly 100 years pre-explosion. The observed diversity demonstrates the power of mid-IR observations of a large sample of SNe.
Receipt of Diagnostic Tests for Breast Cancer: Validity of Self-Reports Among Low-Income, Mostly Latina, Indigent Women

Little is known about the validity of self-reported completion of diagnostic testing after an abnormal breast cancer screening test. This study assesses the validity of self-reported diagnostic follow-up among 819 low-income, mostly Latina, indigent women with a breast abnormality at two public hospitals in Los Angeles County. Survey responses on receipt of a mammogram, ultrasound, fine needle aspiration, surgical biopsy, or clinical breast exam for diagnostic evaluation of the breast abnormality were compared to medical record data. The authors calculated concordance, Cohen’s κ statistic, and sensitivity and specificity. Kappa values indicated slight agreement for mammogram, ultrasound, and clinical breast exam, and moderate agreement for fine needle aspiration and surgical biopsy. Sensitivity of self-reports was high for all tests; specificity was poor for all tests except surgical biopsy. Self-reports of receipt of diagnostic testing for a breast abnormality among low-income, mostly Latina, indigent women are not accurate when compared to medical records.
Comparison of end-to-end bandwidth measurement tools on the 10GigE TeraGrid backbone

Both network managers and grid application users need to maximize the bandwidth utilization of distributed applications in the face of complex interactions between network and system hardware and software along the end-to-end paths. Several software tools exist that attempt to measure end-to-end available bandwidth unobtrusively. Our poster presents results of the first study to compare these tools on a 10GigE network backbone. We use the Inca test harness deployed on the NSF TeraGrid to collect periodic measurements from a fully connected mesh of node pairs on end-to-end paths between eight TeraGrid sites. We compare bandwidth measurements from (1) network weather service (NWS); (2) pathchirp; and (3) pathload. Our poster analyzes collected data to determine tool accuracy and efficiency.

Substance and Predication in Aristotle

This book takes up the central themes of Aristotle's metaphysical theory and the various transformations they undergo prior to their full expression in the Metaphysics. Aristotle's metaphysics is bedevilled by classic puzzles involving such notions as form, predication, universal, and substance, which result from his attempt to adapt the various requirements on primary substance developed in his earlier works so that they fit the very different metaphysical picture in his later work. Professor Lewis argues that Aristotle is himself aware of most if not all of these difficulties and in the Metaphysics works hard to ensure the coherence of his theory. He presents Aristotle's views as a formal theory complete with axioms, definitions, and theorems.
Central compensation of vestibular deficits. II. Influences of roll tilt on different-size lateral vestibular neurons after ipsilateral labyrinth deafferentation.

The activity of 168 Deiters' neurons projecting to lumbosacral segments of the spinal cord has been recorded in precollicular decerebrate cats after ipsilateral acute (aVN) or chronic vestibular neurectomy (cVN), and their response characteristics to sinusoidal stimulation of contralateral labyrinth receptors at the standard parameters (roll tilt at 0.026 Hz, 10 degrees peak displacement) have been related to cell size inferred from the conduction velocity of the corresponding axons. These findings were compared with those elicited in decerebrate cats with both vestibular nerves intact. In all experimental conditions, the higher the coefficient of variation (CV) of the vestibulospinal neurons, reflecting a more irregular unit discharge, the lower was the mean discharge rate at rest. However, the proportion of regularly discharging units (with the lowest CV) decreased after aVN but increased after cVN. The relation found in control experiments, i.e., the faster the conduction velocity of vestibulospinal axon the lower was the unit discharge at rest, was lost after aVN due to a decrease in resting discharge rate of the slow neurons. The mean discharge rate of these units, however, recovered after cVN, so that the negative correlation between resting discharge rate and axonal conduction velocity was reestablished. After aVN, the decrease in resting discharge rate of the slow vestibulospinal neurons was not associated with significant changes in gain (impulses per second per degree) of the unit responses to standard parameters of tilt, so that the sensitivity of these units (percentage change of the mean discharge rate per degree) increased; on the other hand, the resting discharge rate of the fast neurons, which remained almost unchanged after aVN, was associated with a significant increase in gain, thus leading to an average increase in response sensitivity of these units.

Microbiological Analysis of Street Vended Food in

Street food vending has become an important public health issue and a great concern to everybody. The present study was aimed to investigate the hygienic conditions of the vendors and microbial quality of street foods. It was shown that their food handling practices were very poor. For microbial analysis, 5 street foods and 5 franchise's food products were taken from most popular shops. In local street foods, the bacterial load in veg- momos (130±2.1- 34.5±1.5 CFU/g) and non-veg momos (360±2.55-4±0.60 CFU/g) was high than the other samples. In branded food product samples, burger (362.5±2.55 CFU/g), non-veg momos (262.5±2.41-2.0±0.30 CFU/g), veg-mo- mos (85.0±1.92-9.0±0.95 CFU/g), gol-gappa (237.5±2.37- 8±0.90 CFU/g) was seen. The presence of coliform indicated faecal contamination of the processing water as well as the prevailing unhygienic conditions related to the location of food preparation. It is suggested that proper hygienic and sanitary conditions has to be maintained both personally and institutionally to avoid any food-borne pathogenic outbreaks in India, especially in the children and young who are tempted to such food. Therefore, the critical control points should be taken as safe limit by the Government/ authori- ties to reduce the cases of food contamination.
An incentive for coordination in a decentralised service chain with a Weibull lifetime distributed facility

This article deals with a decentralised service chain consisting of a service provider and a facility owner. The revenue allocation and service price are, respectively, determined by the service provider and the facility owner in a non-cooperative manner. To model this decentralised operation, a Stackelberg game between the two parties is formulated. In the mathematical framework, the service system is assumed to be driven by Poisson customer arrivals and exponential service times. The most common log-linear service demand and Weibull facility lifetime are also adopted. Under these analytical conditions, the decentralised decisions in this game are investigated and then a unique optimal equilibrium is derived. Finally, a coordination mechanism is proposed to improve the efficiency of this decentralised system.
A Simple RVoG Test for PolInSAR Data

In this paper, we present a simple algorithm for assessing the validity of the RVoG model for PolInSAR-based inversion techniques. This approach makes use of two important features characterizing a homogeneous random volume over a ground surface, i.e., the independence on polarization states of wave propagation through the volume and the structure of the polarimetric interferometric coherency matrix. These two features have led to two different methods proposed in the literature for retrieving the topographic phase within natural covers, i.e., the well-known line fitting procedure and the observation of the (1, 2) element of the polarimetric interferometric coherency matrix. We show that differences between outputs from both approaches can be interpreted in terms of the PolInSAR modeling based on the Freeman-Durden concept, and this leads to the definition of a RVoG/non-RVoG test. The algorithm is tested with both indoor and airborne data over agricultural and tropical forest areas.
HIV Nef-mediated Cellular Phenotypes Are Differentially Expressed as a Function of Intracellular NEF Concentrations*

Nef is a regulatory protein encoded by the genome of both human and simian immunodeficiency virus. Its expression in T cells leads to CD4 and major histocompatibility complex class I modulation and either enhancement or suppression of T cell activation. How this viral protein achieves multiple and at times opposing activities has been unclear. Through direct measurements of Nef and the Nef-GFP fusion protein, we find that these events are mediated by different Nef concentrations. Relative to the intracellular concentration that down-modulates surface CD4, an order of magnitude increase in Nef-GFP expression is required for a comparable modulation of major histocompatibility complex class I, and a further 3-fold increase is necessary to suppress T cell activation.
Flexible Demand in Smart Grids - Modeling and Coordination

The economic analysis of smart grid capabilities needs to incorporate physical boundaries as hard constraints which need to be facilitated by means of flexibility potentials and intelligent dispatching. Due to the distributed nature of demand, economic coordination also needs to be able to facilitate a multitude of individual agents. Questions concerning the modeling and coordination of an active demand side are addressed using tools and techniques from information systems and economics.

Poster: Localized Content for Village Schools

Studies on global Internet connectivity report that only 40% of the world population has access to the Internet [1]. While Internet connectivity has the potential to provide numerous educational opportunities, there is often a lack of educational content that is relevant with respect to the culture and language of those attending schools in largely disconnected communities. Inspired by the problem of sharing relevant educational content within and between schools, we extend VillageShare to facilitate content sharing between village schools that are networked together via low-bandwidth wireless links. Originally designed to localize social media content in a single community [2], the extended version of VillageShare operates across multiple sites to ensure that relevant educational content is 1) highly available to local users and 2) made globally available using a robust synchronization protocol. This design enables village teachers and students to create regional repositories of relevant digital curricula that are accessible even during network failures and outages.
Activities of daily living: changes in functional ability in three samples of elderly and very elderly people.

OBJECTIVES to investigate changes in functional ability and physical health, psychiatric morbidity, life satisfaction, service use and social support. DESIGN a structured interview survey of three samples of elderly people living at home at two points in time. The three samples comprised one census of people aged 85 and over [City (of London) and Hackney], and two random samples of people aged 65-84 (City and Hackney and Braintree). The follow-up interviews took place 2.5-3 years after the baseline interviews. SETTING City and Hackney (East London) and Braintree (Essex). Respondents were interviewed at home by one of 12 trained interviewers. SUBJECTS 630 people aged 85+ at baseline (70% response rate) and 78% of survivors re-interviewed at follow-up; 464 people aged 65-84 in Hackney at baseline (67% response rate), and 83% of survivors re-interviewed; 276 people aged 65-84 in Braintree at baseline (82% response rate), and 78% of survivors re-interviewed. MAIN OUTCOME MEASURES scores on scales of functional ability, psychiatric morbidity, life satisfaction and social support, and items measuring number and type of health symptoms and services used. CONCLUSIONS decreasing levels of physical functioning were associated with poor mental health, trouble with feet and problems with muscles and joints. There were no associations with level of physical functioning and use of rehabilitative or general medical services, use of social worker or carer relief. Few respondents used preventive or rehabilitation services.
Phenolic Acids Composition of Fruit Extracts of Ber (Ziziphus mauritiana L., var. Golo Lemai)

Fruits of Ziziphus mauritiana L. (ber) are consumed in fresh and dried/processed form in many countries across Asia including Pakistan. In the present study, we analyzed the composition of total phenolic acids (free, soluble-bound and insoluble-bound) from ber fruit extracts by applying a pressurized liquid base hydrolysis extraction (PLBHE) using Dionium cells. Nine phenolic acids (protocatechuic, p-hydroxybenzoic, ferulic, chlorogenic, vanillic, caffeic, vanillin, o- and p- coumaric acids) were extracted, separated, and quantified by HPLC-DAD. Identification of phenolic acids was achieved by comparison of retention times, ultraviolet, and mass spectral data with authentic commercial standards. Results showed that p-coumaric acid (3719 ± 22 µg/g) was the predominant phenolic acid extracted from ber samples. In addition, four phenolic acids, namely p-hydroxybenzoic (2187 ± 71 µg/g), vanillin (2128 ± 20 µg/g), ferulic (2629 ± 96 µg/g), and o-coumaric acids (2569 ± 41 µg/g) were obtained in intermediate amounts from dried Ziziphus mauritiana L. fruit. The total phenolic acids content was determined as 18231 ± 306 µg/g dry matter basis (DMB). This study indicates that ber fruit is a good natural source of phenolic acids and that PLBHE can be used for the assay of phenolic acids.
Delegated Monitoring and Contracting

In a dynamic agency model, investors finance a firm run by an agent while delegating monitoring and contracting with the agent to an intermediary. The intermediary passes through part of its incentives to the agent. After good performance, the agent's incentives create an agency overhang problem, that is, the reduced incentives of the intermediary for monitoring because its benefit accrues mostly to the agent. Conversely, after poor performance, the agent's incentives generate incentives for monitoring to avoid further distress. Investors can benefit from directly contracting with the agent to prevent propagating agency conflicts between the agent and the intermediary.
