Optical Diagnostic Study on Improving Performance and Emission in Heavy-Duty Diesel Engines Using a Wave-Shaped Piston Bowl Geometry and Post Injection Strategies

This study explores the potential benefits of combining a wave-shaped piston geometry with post injection strategy in diesel engines. The wave piston design features evenly spaced protrusions around the piston bowl, which improve fuel-air mixing and combustion efficiency. The ‘waves’ direct the flames towards the bowl center, recirculating them and utilizing the momentum in the flame jets for more

A Theory of Value for Value-Based Feature Selection in Software Engineering

Value-Based Software Engineering stresses the role of value in software related decisions. In the context of feature selection, software features judged to provide higher value take priority in the development process. This paper focuses on what value means when selecting software features. Using grounded theory, we conducted and analyzed semi-structured interviews with 21 key stakeholders (decisi

Recruitment of pre-dementia participants : main enrollment barriers in a longitudinal amyloid-PET study

Background: The mismatch between the limited availability versus the high demand of participants who are in the pre-dementia phase of Alzheimer’s disease (AD) is a bottleneck for clinical studies in AD. Nevertheless, potential enrollment barriers in the pre-dementia population are relatively under-reported. In a large European longitudinal biomarker study (the AMYPAD-PNHS), we investigated main en

Cross-section measurements for the production of a Z boson in association with high-transverse-momentum jets in pp collisions at √s = 13 TeV with the ATLAS detector

Cross-section measurements for a Z boson produced in association with high-transverse-momentum jets (p T ≥ 100 GeV) and decaying into a charged-lepton pair (e + e − , μ + μ −) are presented. The measurements are performed using proton–proton collisions at s = 13 TeV corresponding to an integrated luminosity of 139 fb −1 collected by the ATLAS experiment at the LHC. Measurements of angular correlat

Time for some changes to ICIS? Reflections on our highest-quality conference

In this commentary, we reflect on the program chair experience of ICIS 2015 to pass on some useful organizational memory for the IS community at large. We also reflect on volunteer effort required for a high-quality conference and the challenges of maintaining quality over a diverse and dispersed reviewing effort. We ask whether we can count on this volunteer effort in a changing higher education

Announcement Effect of Primary Seasoned Equity Offerings of Common Stock: Evidence from the Swedish Stock Market

This study investigates the abnormal returns associated with announcements of primary seasoned equity offerings of common stock on the Swedish stock market. It provides a comprehensive discussion on equity offerings and their related theories, in addition to a thorough review of existing empirical research. Based on our event study analysis of data on rights and directed offerings for firms listed

Value-at-risk of Vietnamese banks' stocks: Investigating the relationship with bank-specific characteristics

The purpose of this study is to investigate the relationship between Value at Risk (VaR) and bank-specific characteristics within the Vietnamese financial market, a rapidly growing yet risk-exposed sector. The study uses VaR as a measure of market risk and other characteristics of bank as a proxy for banks’ market power, profitability, risk, solvency, efficiency, and ownership. The study utilizes

Amidst an Urban Archive and Rustling Wind: Of Mediation in Digital and Nonsite Performance Environments.

This presentation departs from two recent collaborative projects. The former An Urban Archive as an English Garden (Franzson, 2019) was instigated by Davíð Brynjar Franzson and revolved around a sonic hologram and performance therein. The second project, Violin with Þytur (Olofsson & Stefánsdóttir, 2021) was a collaboration with Kent Olofsson which resulted in a performance within the nine mon

Electronic pedagogy and future university business models

Based on the International Conference on Information Systems’ (ICIS) 2014 senior scholars’ forum, we share insights on the relationship between evolving university business models and the adoption of electronic pedagogy. In recent years, particularly with the initiation of MOOCs, the potential for delivering high-quality and widely distributed coursework has expanded. However, particular instances

Exceptions and limitations (27 UPCA)

The UPCA for the first time establishes harmonized exceptions and limitations to the effects of granted patent rights. Previously these were the sole province of national law but a with a degree of similarity.This chapter briefly analyses the historical origin, legal nature and scope of Article 27 UPCA, the future harmonizing effect of UPCA patent limitations, followed by a discussion on each limi

Vertical III-V Nanowire Tunnel Field-Effect Transistors : A Circuit Perspective

The energy scaling of integrated circuits has reached its limit because the operating voltage of Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFET) based switches has reached its minimum value. MOSFETs are limited by thermionic emission and cannot achieve a subthreshold swing (SS) below 60 mV/decade at room temperature. Tunnel Field-Effect Transistors (TFET), which operate on field modula

Predicting the Movement of the S&P 500 Index using Machine Learning

Predicting the stock market has been a longstanding topic of interest in financial research. It is regarded as a highly challenging but important task given the vital role the financial markets play in shaping the global economies. In this thesis, the goal is to predict the movement of the S&P 500 Index using machine learning methods. To this end, we apply two machine learning algorithms, rand

Cyclosporine as Therapy for Traumatic Brain Injury

Drug development in traumatic brain injury (TBI) has been impeded by the complexity and heterogeneity of the disease pathology, as well as limited understanding of the secondary injury cascade that follows the initial trauma. As a result, patients with TBI have an unmet need for effective pharmacological therapies. One promising drug candidate is cyclosporine, a polypeptide traditionally used to a

Do central bank speeches help predict monetary policy?

This paper studies the information contained in central bank speeches, focusing on predicting future monetary policy. Departing from previous papers which use mainly dictionary-based methods, we employ the deep transfer learning technique to process the text data. We find that central bank speeches can be used to predict policy rate change over the next three months (with an accuracy of 71.4%). In

Modelling Airbnb Prices in the Maltese Islands

The digital platform Airbnb has gained popularity in a number of countries particu- larly in the Maltese islands. Striking a balance in setting a price that is competitive and also renders a good profit can be a challenge. In this thesis a model is de- veloped to predict the price of a listing in the Maltese islands for September 2022 through a machine learning approach whereby five types of model
