Ohjelmistoturvallisuuden parantaminen staattisella analyysillä

2018

Staattisella analyysillä tarkoitetaan ohjelmiston ominaisuuksien tarkastelemista kääntämättä tai ajamatta ohjelmistoa. Tämä tutkielma on pienimuotoinen kirjallisuuskatsaus, jonka tarkoituksena on lähdekirjallisuutta tutkimalla ja jäsentämällä tutkia, miten staattisella analyysillä voidaan parantaa nykyaikaisten web-applikaatioiden ohjelmistoturvallisuutta. Tutkitun kirjallisuuden perusteella staattista analyysiä hyödyntävillä työkaluilla on mahdollista havaita yleisiä, liiketoiminnan kannalta erittäin tuhoisia haavoittuvuuksia ja täten parantaa merkittävästi ohjelmistoturvallisuutta. Näiden työkalujen tehokas hyödyntäminen ohjelmistokehityksen kontekstissa vaatii kuitenkin suunnitelmallisuu…

Perceptions, motives, and psychological flexibility associated with weight management

2012

Introduction: Overweight people are often able to lose weight with the help of professionals, but majority (about 85 %) of the weight losers fail to maintain behavioral changes that would lead to favorable results in the long term [1‐3]. Studies suggest that obesity treatment failures may reflect motivational and contextual impediments to weight loss, rather than limitations of the behavior change strategies per se [4, 5]. A stronger emphasis on motivational factors within a behavioral weight maintenance program offers promise for improving long-term outcomes. The motivation-focused approach has been shown to be as effective as the successful standard skill-based method in weight maintenanc…

Built Environment and Wellbeing—Standards, Multi-Criteria Evaluation Methods, Certifications

2022

The debate on IEQ (Indoor Environmental Quality), with a focus on the healthiness of the built environment and its possible influence on the natural environment, has been a relevant topic for a decade. This interest has expanded to the quality of building technologies, specifically their performances and environmental effects. The objectives set by the 2030 Agenda have led to overcome the idea that sustainability is only related to environment; instead, a holistic vision aimed at human health has been affirmed (objective 3). The period marked by the Covid19 emergency contributed to strengthen the need for human well-being, as the “quarantine” made us observe our living spaces, r…

Importazione massale di dati in Wikiplantbase: l'esperienza con Wikiplantbase #Sicilia

2019

Il progetto Wikiplantbase è stato avviato nel 2013 al fine di offrire un sistema dove caricare record floristici georeferenziati, liberamente accessibili via internet. Sino ad allora, infatti, esistevano un gran numero di banche dati online sulla nomenclatura, tassonomia, erbari, specie aliene, vegetazione, numeri cromosomici e sequenze di DNA, ma non vi era facile accesso ai dati floristici a grande dettaglio geografico. I record floristici costituiscono i dati primari sulla biodiversità utili per qualsiasi ricerca di biologia vegetale. Al fine di aumentare i dati sulla Sicilia disponibili in Wikiplantbase, si sono elaborati e standardizzati alcuni dei dati liberamente accessibili dal sito…

Practice for determining friction in hydraulic winch systems

2020

This paper presents a method for estimating friction in hydraulic active heave compensated (AHC) offshore winches. The method is a two-step approach where the first step is to model the friction loss in the hydraulic motors based on data from the sub-supplier. The second step requires real-life testing, where the remaining friction losses in the winch system is identified and modeled. In this context, a practice is characterized by obtaining a friction loss estimation with the highest possible accuracy over the widest possible range of operating conditions with a limited amount of experimental work. The method benefits from the use of parametric models, sub-supplier data, and real-life meas…

Learn to Cache: Machine Learning for Network Edge Caching in the Big Data Era

2018

The unprecedented growth of wireless data traffic not only challenges the design and evolution of the wireless network architecture, but also brings about profound opportunities to drive and improve future networks. Meanwhile, the evolution of communications and computing technologies can make the network edge, such as BSs or UEs, become intelligent and rich in terms of computing and communications capabilities, which intuitively enables big data analytics at the network edge. In this article, we propose to explore big data analytics to advance edge caching capability, which is considered as a promising approach to improve network efficiency and alleviate the high demand for the radio resou…

IEEE Access Special Section Editorial: Exploiting the Benefits of Interference in Wireless Networks: Energy Harvesting and Security

2018

Interference used to be viewed as a harmful factor in wireless networks, which can reduce the quality of information transmission. To combat against interference, many interference management techniques have emerged. Due to the latest research advances, interference (or noise) can also be exploited to offer some benefits to wireless networks. The first aspect is that interference in multi-user networks can be collected as a green power supply for the transceivers, known as wireless energy harvesting. Another application is that one can generate artificial noise to disrupt the adversarial eavesdropping, and guarantee the security of wireless networks. Therefore, conventional interference man…

Underwater Multirobot Cooperative Intervention MAC Protocol

2020

This work introduces a Medium Access Control (MAC) protocol designed to allow a group of underwater robots that share a wireless communication channel to effectively communicate with each other. The goal of the Underwater Multirobot Cooperative Intervention MAC (UMCI-MAC) protocol presented in this work is to minimize the end to end delay and the jitter. The access to the medium in UMCI-MAC follows a Time Division Multiple Access (TDMA) strategy which is arbitrated by a master, which also has the capability to prioritize the transmission of some nodes over the rest of the network. Two experiments have been carried out with a team of four Autonomous Underwater Vehicles (AUV) in order to comp…

Trajectory Design and Resource Allocation for Multi-UAV Networks : Deep Reinforcement Learning Approaches

2023

The future mobile communication system is expected to provide ubiquitous connectivity and unprecedented services over billions of devices. The unmanned aerial vehicle (UAV), which is prominent in its flexibility and low cost, emerges as a significant network entity to realize such ambitious targets. In this work, novel machine learning-based trajectory design and resource allocation schemes are presented for a multi-UAV communications system. In the considered system, the UAVs act as aerial Base Stations (BSs) and provide ubiquitous coverage. In particular, with the objective to maximize the system utility over all served users, a joint user association, power allocation and trajectory desi…
