Large scale secure automatic provisioning of X.509 certificates via web services
Year: 2015

The subject of this thesis is the efficient deployment of Public Key Infrastructures (PKI) more specifically, a way to securely and automatically provide and deploy X.509 certificates, using web services as a mean of communication between the Certicate Authority and end entities. This is highly relevant since more and more organizations are using PKI services in order to, for example, securely communicate through insecure channels like the Internet, digital signing operations or to provide non repudiation properties to protocols and information systems. Although PKI technologies have become pervasive among most institutions, there are still very few well known protocols that support automatic certificate provisioning; the Simple Certificate Enrollment Protocol (SCEP) and the Automatic Certificate Management Environment (ACME) However SCEP suffers from some security flaws and ACME is highly focused on a single PKI application domain. We examined the problem and tried to understand if it is possible to more generally deploy such an automatic service and to what extent these generalizations can be considered secure. The thesis begins with a constructive research to analyze existing solutions, and from the research made, we devise and implement a fully working solution that we think satisfies our initial goals. In this thesis we present and describe a fully implementation of an architecture to deploy such a service. Our system relies on the delivery of security elements, such as cryptographic tokens or smartcards containing an administrative certificate, to the PKI end entities, as a security anchor. We have also developed a framework architecture for PKI backoffice services, a data model for end entity interactions with the backoffice PKI services and a secure Remote Procedure Call based API for end entity client software to use for the automatic

Autothermal recirculating reactor (ARR) with Cu BN composite as a stable reactor material for sustainable hydrogen release from ammonia
Year: 2021

Ammonia (NH3) has been proposed as a viable hydrogen (H2) carrier, but high reaction temperature and endothermic nature of NH3 decomposition require an efficient reaction system to maximize useable energy from NH3. Adoption of carbon free heat sources and efficient heat transfer to the reaction bed are crucial for sustainable H2 release. Herein, the autothermal recirculating reactor (ARR) concept with the fractional utilization of the reformate H2 as a clean combustion fuel is proposed and experimentally investigated. Additionally, BN coated Cu as a composite reactor material is developed for heat transfer enhancement of high temperature H2 release reaction in a thermally coupled NH3 decomposition and H2 combustion system. Coating performance against chemical degradation of Cu has been tested and confirmed. High NH3 conversion of >99.6% and reforming efficiency of 70.95% even with high fraction of heat loss owing to small scale validation, show feasibility of the as proposed reformer. Operation of the suggested system is envisaged with self sustained heat supply for production of 84 W of electrical power. Also, the as proposed reactor concept and material are suggested to serve in other endothermic H2 release reactions from various H2 carriers (methane, methanol, LOHC, etc) for potential application in power generation as well as high purity H2 production.
Role of timbre and fundamental frequency in voice gender adaptation.
Venue: The Journal of the Acoustical Society of America
Year: 2015

Prior adaptation to male (or female) voices causes androgynous voices to be perceived as more female (or male) Using a selective adaptation paradigm the authors investigate the relative impact of the vocal fold vibration rate (F0) and timbre (operationally in this paper as characteristics that differentiate two voices of the same F0 and loudness) on this basic voice gender aftereffect. TANDEM STRAIGHT was used to morph between 10 pairs of male and female speakers uttering 2 different vowel consonant vowel sequences (20 continua) Adaptor stimuli had one parameter (either F0 or timbre) set at a clearly male or female level, while the other parameter was set at an androgynous level, as determined by an independent set of listeners. Compared to a control adaptation condition (in which both F0 and timbre were clearly male or female) aftereffects were clearly reduced in both F0 and timbre adaptation conditions. Critically, larger aftereffects were found after timbre adaptation (comprising androgynous F0) compared to F0 adaptation (comprising an androgynous timbre) Together these results suggest that timbre plays a larger role than F0 in voice gender adaptation. Finally, the authors found some evidence that individual differences among listeners reflect in part pre experimental contact to male and female voices.
The agent based Solow growth model with endogenous business cycles
Year: 2015

This article describes a simulated monetary macro model with different types of interacting agents. As such, it is assigned to the field of agent based computational economics (ACE) where agents become virtual objects in a computer simulation. The ACE model core with labor market and goods market interaction between households and firms is adopted from Lengnick (2013) whereas production technology and technological progress of firms are adopted from the neoclassical Solow (1956) model. Nominal interest rates are set in accordance with the Taylor (1993) principle, characterized by strong responses of monetary policy to deviations from inflation target. Although inflation desirably follows lagged output in a pro cyclical manner, the dynamic system allows for long run stability of inflation rates. Firms on aggregate level endogenously generate waves of higher and lower investment. A recurrent cyclical movement of aggregate economic activity, in particular demand, employment and inflation, is transmitted from these waves of investment activity. Cyclical patterns of boom and bust emerge with a frequency of approximately seven years just like Juglar type cycles. Moreover, the model generates a short run Phillips curve relationship, long run neutrality of monetary policy and business cycle patterns similar to the Goodwin (1967) model. Fiscal stabilization policy is shown to dampen macroeconomic fluctuations, thus allowing for a higher level of average employment. Calibration of model parameters is conducted to generate realistic orders of magnitude of important macroeconomic proportions. The newly developed model is a combination of ideas from different economic perspectives and contributes to macroeconomic model building under the paradigm of agent based computational economics.
Mnemonic emotion regulation: a three process model
Venue: Cognition emotion
Year: 2019

Emotion regulation comprises attempts to influence when and how emotions are experienced and expressed. It has mostly been conceived of as proactive (e.g. situation selection) or reactive (e.g. attentional distraction) but it may also be retroactive and involve memory. I term such past oriented activity mnemonic emotion regulation and propose that it involves increasing or decreasing access to or altering the characteristics of a memory. People may increase access to a memory and make it more likely that it will be retrieved in the future, for example by rehearsing a pleasant memory. They may decrease access to a memory and make it less likely that intrusions will be experienced in the future, for example by repeatedly trying to stop an unpleasant memory from being retrieved. Finally, people may alter the characteristics of a memory and change its content or context, for example by replacing a negative impression with a productive interpretation. I discuss how mnemonic emotion regulation may be instigated (e.g. via elaborate rehearsal) as well as the different motives (e.g. hedonic motives) people may have for engaging in regulation. Also, I discuss possible benefits of, variations in, and improvements of mnemonic emotion regulation.

Year: 2015

This paper analyzes the adoption and welfare impacts of improved maize varieties in eastern Zambia using data obtained from a sample of over 800 farm households. Using both propensity score matching and endogenous switching regression models, the paper shows that adoption of improved maize leads to significant gains in crop incomes, consumption expenditure, and food security. Results further show that improved maize varieties have significant poverty reducing impacts in eastern Zambia. The paper concludes with implications for policies to promote adoption and impacts of modern varieties in Zambia.
Reply to the Letter to the Editor: infection control protocol inside computed tomography suites during coronavirus disease 2019 outbreak
Venue: Japanese Journal of Radiology
Year: 2020

I would like to express my gratitude to Dr. Joob and Dr. Wiwanitkit for their thoughtful letter regarding our report  As they suggested, the risk faced by radiologists, radiologic technologists, and nurses who practice in the computed tomography (CT) suites is a critical issue. It is challenging for most hospitals to renovate the CT suite for scanning patients infected with the novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS CoV 2) It is considered that the person to person transmission is mainly caused by droplet or contact transmission  and donning the appropriate personal protective equipment (PPE) and sanitizing with alcohol based disinfectants may be adequate to prevent in CT suite transmission. In contrast, van Doremalen et al.  reported the possibility of aerosol and fomite transmission of SARS CoV 2. Therefore, when respiratory intensive care, e.g. endotracheal intubation, is performed in the CT suite for a coronavirus disease 2019 patient with serious respiratory insufficiency, the CT suite should be nonoperational for 2 3 h. This measure is for air change to occur after the patient has left the CT suite to avoid aerosol and fomite transmission. The current situation has changed, and another serious problem has risen. The stock of PPE was sufficient at the time of submission of our report  but the PPE shortage has increased the risk of infection for the medical staff. The support of the government may be necessary to address this problem that confronts us.

Realizing an efficient fusion gate for W states with cross Kerr nonlinearities and QD cavity coupled system
Venue: Quantum Inf. Process.
Year: 2015

We propose a new scheme for fusing two arbitrary size photonic W states encoded by polarizations to generate a larger W state. With the help of cross Kerr nonlinearities and a quantum dot in an optical cavity (QD cavity coupled system) we can realize the fusion of W states with a high success probability. In addition, the scheme does not need any ancillary photon, and it can also be applied to fuse two Bell states. The scheme can be realized with current experimental technology.
Quality of life, effects on Asian Lifestyle, and perceived satisfaction after total hip arthroplasty in Japan and Korea.
Venue: International journal of orthopaedic and trauma nursing
Year: 2018

The Asian lifestyle requires deep hip flexion, which increases the risk of dislocation. Hence, Asian total hip arthroplasty (THA) patients may have problems postoperatively. This study aimed to 1) document quality of life (QoL) Asian lifestyle related items (five postures that require deep hip flexion) and perceived satisfaction in patients who underwent THA in Japan versus Korea, 2) assess the differences in QoL and Asian lifestyle related items by patient lifestyle, and 3) identify the factors predicting QoL.  This cross sectional study included 222 THA patients. Korean patients completed the questionnaires. Japanese patients were then matched with Korean patients by age, sex, and post THA period. Assessed parameters included QoL measured by the EuroQoL, Oxford hip score (OHS) Asian lifestyle (measured by the Asian lifestyle related items) and perceived satisfaction (measured by the five items of postoperative satisfaction) Multiple regression analysis was used to determine the predictors of QoL.  Compared with Korean patients, Japanese patients had better QoL, but more difficulty performing postures requiring deep hip flexion. Greater QoL was associated with greater satisfaction. The predictors of decreased QoL after THA were lower OHS in both countries, worse squatting ability in Japan, and worse leg crossing ability in Korea.  In Japan and Korea, the OHS is an important predictor of QoL after THA.
From Taylor to Tyler to No Child Left Behind: Legitimating educational standards
Year: 2015

In the early 20th century, proponents of the so called "social efficiency movement" in the United States tried to apply methods and concepts for enhancing efficiency in industrial production to the organization of teaching and learning processes. This included the formulation of "educational standards" analogous to industrial standards. While the concept of educational standards now has advocates in many parts of the world, today's rationales for standards based reform differ strongly from those put forward then. In a series of "snapshots" this article traces the changes in the ways educational standards and standards based reform were legitimated over the course of the 20th century. It focuses on the United States, but as standards based reform has become a truly global phenomenon, it also discusses educational standards as they have been implemented in Sweden.
A Software Application for Automatic Characterization of Piezoresistive MEMS Pressure Sensors
Year: 2017

In order to improve the efficiency of the pressure sensors characterization process at the Center of Microelectronic Technologies (CMT) a new measurement setup is developed that enables fully automatic characterization of multiple silicon piezoresistive MEMS pressure sensors. The whole experiment, including high performance measurement of sensors output signals at several temperature and pressure values, and storage of the measured results in a computer file, requires only a minimum of operator action. The setup consists of both hardware and software modules. The hardware is partly based on equipment designed and built at CMT for this purpose, and the software is entirely developed at CMT. This paper is focused on the software aspects of the developed experimental setup. The main objective of the presented work is to make the small series production of industrial pressure transmitters at CMT more efficient. The results are also very useful for research and development of pressure sensors and instrumentation.
Ok, we have the Resources, But what Next? A Conceptual Model of the Effects of Project Team Activities on Customer Perceived Value
Year: 2015

Service dominant logic provides a framework for understanding buyer supplier exchange. One of its key claims is that operand resources, when combined with operant resources facilitate the creation of value. While this conceptualisation provides an interesting framework for the assessment of value creation, it does not capture the specific activities performed by operant resources. I argue that a gap exists in SDL in that it does not address resource application. Further, the understanding of value is vague. It does not capture the non financial or non functional value drivers held by customers. This exploratory study defines four broad categories of activities (the application of resources) performed by project teams in medium and large scale service deliveries. It then proposes a framework that identifies the effects of these behaviours on customer perceived value as well as potential moderators of those relationships. These findings derive from a webethnography based on the professional social networking site www.Linkcdln.com. The paper discusses these findings and offers suggestions for future research.
Glycosyltransferases: structures, functions, and mechanisms.
Venue: Annual review of biochemistry
Year: 2008

Glycosyltransferases catalyze glycosidic bond formation using sugar donors containing a nucleoside phosphate or a lipid phosphate leaving group. Only two structural folds, GT A and GT B, have been identified for the nucleotide sugar dependent enzymes, but other folds are now appearing for the soluble domains of lipid phosphosugar dependent glycosyl transferases. Structural and kinetic studies have provided new insights. Inverting glycosyltransferases utilize a direct displacement S(N)2 like mechanism involving an enzymatic base catalyst. Leaving group departure in GT A fold enzymes is typically facilitated via a coordinated divalent cation, whereas GT B fold enzymes instead use positively charged side chains and/or hydroxyls and helix dipoles. The mechanism of retaining glycosyltransferases is less clear. The expected two step double displacement mechanism is rendered less likely by the lack of conserved architecture in the region where a catalytic nucleophile would be expected. A mechanism involving a short lived oxocarbenium ion intermediate now seems the most likely, with the leaving phosphate serving as the base.
q Calculus Formalism for Non extensive Particle Filter
Year: 2019

A class of sequential Monte Carlo estimation is frequently called particle filter. This filter belongs to the Bayesian strategy for estimation, where a non linear and non Gaussian assumptions can be applied. Here, the Tsallis' distribution, from the non extensive thermo statistics, is used to design the best likelihood operator. Therefore, no previous likelihood operator is assumed. The new filter formulation will be named as non extensive particle filter (NEx PF) The distribution estimated by the NEx PF can compute the standard form of the central limit theorem, as well as the Levy Gnedenko central limit theorem. The q calculus formalism is employed to generalize some definitions and properties.
Biomass derived carbon helices induced phase transition in poly(N ispropylacrylamide) A sustainable tailoring of coil globule transition in thermoresponsive polymer.
Venue: Colloids and surfaces. B, Biointerfaces
Year: 2019

Functional carbon helices (FCHs) containing various oxygenated functionalities derived directly from lignocellulosic biomass is proved to be a potential eco friendly candidate for biomolecules. No study reports the effect of biomass derived platform molecules on the thermoresponsive behavior of polymers, which have been proved potential candidates in carrying various drug delivery applications, gels, and tissue engineering in this vast area of research. Poly(N isopropylacrylamide) (PNIPAM) is a thermoresponsive polymer that has been found to be a prevailing tool in carrying various aforesaid applications. This study reports a powerful impact on the thermoresponsive behavior of PNIPAM by a non hazardous alternative form of a herbecious plant Parthenium hysterophorus. Fluorescence spectroscopy was deployed to study the microenvironment provided by carbon helices around the polymer structure. The results obtained are directly correlating with the increased polarity with higher concentration of FCHs and further confirmed a decrease in fluorescence intensity. Moreover, for better understanding of interactions between PNIPAM and FCHs, Fourier transform infrared spectroscopy (FTIR) was employed. The analysis of hydrodynamic diameter (dH) was carried out by dynamic light scattering (DLS) and the aggregate size of PNIPAM was found to increase in higher concentration of FCHs. A decrease from 34.7 degC to 29.0 degC in the lower critical solution temperature (LCST) of PNIPAM in FCHs was further confirmed by differential scanning calorimetry (DSC) Field emission scanning electron microscopy (FESEM) and Transmission electron microscopy (TEM) were also taken into account to understand the morphological changes of PNIPAM in presence of biomass derived carbon helices. The micrographs of PNIPAM biomass are representing a perturbed morphology of PNIPAM during interaction with FCHs. In this study, high degree of oxygenated functionalities on the carbon helices has a meaningful impact on the conformational phase behavior of PNIPAM. The tendril like functional carbon helices (TLFCHs) are uniquely causing a decrease in the lower critical solution temperature (LCST) of PNIPAM. Our combined study indicates that biomass derived carbon helices significantly decrease the LCST of PNIPAM by 5 degC. Ultimately, the polymer achieves compact globule conformational and complete aggregated state.
