Abstract:
In this paper, we provide an interpretation of the rationality in game theory in which player consider the profit or loss of the opponent in addition to personal profit at the game.‎ ‎‎The goal of a game analysis with two hyper-rationality players is to provide insight into real-world situations that are often more complex than a game with two rational players where the choices of strategy are only based on individual preferences. The hyper-rationality does not mean perfect rationality but an insight toward how human decision-makers behave in interactive decisions. ‎‎The findings of this research can help to enlarge our understanding of the psychological aspects of strategy choices in games and also provide an analysis of the decision-making process with cognitive economics approach at the same time.‎ ‎‎‎

Abstract:
Choice is a sine qua non of contemporary life. From childhood until death, we are faced with an unending series of choices through which we cultivate a sense of self, govern conduct, and shape the future. Nowadays, individuals increasingly experience and enact consumer choice online through web-based platforms such as Yelp.com , TripAdvisor.com and Amazon.com . These platforms not only provide a sprawling array of goods and services to choose from, but also reviews, ratings and ranking devices and systems of classification to navigate this landscape of choice. This paper suggests a radical reconsideration of platform architectures and design features to consider how they reconfigure and respecify choice, ‘choosers’, and choice-making practices. Platforms are not simply cameras that present choice and enable comparisons between different options, but are more akin to engines that govern, drive and expand choice, configuring users within particular discourses, practices and subjectivities. In making sense of the entangled trajectories of consumer choice, platform architectures and Big Data, I suggest that ‘hyper-choice’ emerges as a condition of the contemporary platform-driven web. I examine hyper-choice not only in terms of the relationship between platforms and a growing abundance of choice, but more importantly how platforms reconfigure choice in ways that go beyond and fundamentally challenge existing understandings of what choice is, who and what is involved in producing knowledge about choice, and what it means to be a ‘chooser’.

Abstract:
Hyper-heuristics are a subclass of high-level research methods that function in a low-level heuristic research space. Their aim objective is to improve the level of generality for solving combinatorial optimization problems using two main components: a methodology for the heuristic selection and a move acceptance criterion, to ensure intensification and diversification [1]. Thus, rather than working directly on the problem's solutions and selecting one of them to proceed to the next step at each stage, hyper-heuristics operates on a low-level heuristic research space. The choice function is one of the hyper-heuristics that have proven their efficiency in solving combinatorial optimization problems [2–4]. At each iteration, the selection of heuristics is dependent on a score calculated by combining three different measures to guarantee both intensification and diversification for the heuristics choice process. The heuristic with the highest score is therefore chosen to be applied to the problem. Therefore, the key to the success of the choice function is to choose the correct weight parameters of its three measures. In this study, we make a state of the art in hyper-heuristic research and propose a new method that automatically controls these weight parameters based on the Boltzmann function. The results obtained from its application on five problem domains are compared with those of the standard, modified choice function proposed by Drake et al. [2,3].

Abstract:
An important step when using some data assimilation methods, such as the ensemble Kalman filter and its variants, is to calibrate its parameters. Also called hyper-parameters, these include the model and observation errors, which have previously been shown to have a strong impact on the performance of the data assimilation method. Many metrics can be used to calibrate these hyper-parameters but may not all yield the same optimal set of values. The current study investigated the importance of the choice of metric used during the hyper-parameter calibration phase and its impact on discharge forecasts. The types of metrics used each focused on discharge accuracy, ensemble spread or observation-minus-background statistics. The calibration was performed for the ensemble square root Kalman filter over two catchments in Canada using two different hydrologic models per catchment. Results show that the optimal set of hyper-parameters depended heavily on the choice of metric used during the calibration phase, where data assimilation was applied. These sets of hyper-parameters in turn produced different hydrologic forecasts. This influence was reduced as the forecast lead time increased, because of not applying data assimilation in the forecast mode, and accordingly, convergence of model state ensembles produced in the calibration phase. However, the influence could remain considerable for a few days up to multiple weeks depending on the catchment and the model. As such, a preliminary analysis would be recommended for future studies to better understand the impact that metrics can have within and outside the bounds of hyper-parameter calibration.

Abstract:
Deep neural networks are rapidly gaining popularity. However, their application requires setting multiple hyper-parameters, and the performance relies strongly on this choice. We address this issue and propose a robust ex-ante hyper-parameter selection procedure for the day-ahead electricity price forecasting that, when used jointly with a tested forecast averaging scheme, yields high performance throughout three-year long out-of-sample test periods in two distinct markets. Being based on a grid search with models evaluated on long samples, the methodology mitigates the noise induced by local optimization. Forecast averaging across calibration window lengths and hyper-parameter sets allows the proposed methodology to outperform a parameter-rich least absolute shrinkage and selection operator (LASSO)-estimated model and a deep neural network (DNN) with non-optimized hyper-parameters in terms of the mean absolute forecast error.

Abstract:
Sensory as a vehicle of information is today a relevant topic. For many years, the immediacy and spontaneity of the visual approach has supported several theories affirming living in a real “eye culture”. Nowadays, these theories are overtaken, and architects and designers are more and more willing to enclose all the multisensory aspects in their projects. In this context, in Politecnico di Torino developed SounBe, an innovative-patented tool and method conceived in support to the selection of the most suitable materials within the possible hyper-choice, taking into consideration also the sound as a project requirement. Nevertheless, an effective validation of the efficacy of SounBe tool and method was still lacking. Therefore, the aim of the Doctorate research was to validate SounBe tool and method, verify its accuracy as a design tool as well as the effectiveness of the subjective tests performed following its method, and find out any possible improvement. A huge experimental phase was carried out in the anechoic chambers in Politecnico di Torino and IRCAM (Institut de Recherche et Coordination Acoustique/Musique) in Paris. The workspace was selected as testing ground because of the existing relationship between the acoustic conditions of the work environment and workers’ health, job satisfaction and wellbeing; office chair rolling sounds represented the main case-study of the experimentation. More than ninety subjects took part to different listening tests performed in ecologic, laboratory and SounBe conditions, comparing from time to time the results of the descriptive processes adopted to give a qualitative characterization to the sound. Subjective data were compared to objective measures, to better interpret the qualitative judgement. The key point of the validation was demonstrated: the comparability of sounds obtained with the SounBe method and from the real object in action, which was assumed as a reference, was proved. Moreover, a second objective of the research was looking for a possible implementation of the method. Therefore, a set of tests adopting the semantic differential technique were performed, disclosing the possibility to adopt also this technique to sounds obtained with SounBe tool. A final step of this Doctorate research consisted in a direct comparison with enterprises, in order to verify the potential interest of firms in investing on this innovative technology. In this context, the positive feedback as well as its acceptance by firms let hypothesize new activities to carry out after the Doctorate research. Some possible future steps could be finalized to the realization of a new working prototype, as well as the launch of a starting exploitation phase of the technology.

Abstract:
AbstractMore and more nowadays, the Circular Economy is at the heart of European public policies. As a result of the “Next Generation EU” Recovery Plans, a huge amount of financial resources will be available in the coming years to give shape the concept of “ecological transition". For that purpose, radical vision and operational concreteness are needed.In order to strengthen the territorial dimension of public policies aimed at ecological transition, the paper points to consider the status quo of the European territory, looking for recurring elements and differences. In this perspective, a return of “hard” urban studies, focusing on the issues of land ownership, land parcelling, infrastructural and urbanization procedures (and their relationships with the environment and the landscape) should be conducted at the European scale.A central role for the future of contemporary territories is recognized in the so-called “fringe area”, the part of the urban region where patterns of building development and unbuilt space interwave: its intermediary character, as a place between the compact city and the suburban countryside, makes this zone favourable to the collaboration between the two worlds. In addition, its easy accessibility from both the denser contexts and the outer areas makes it the perfect place to locate the equipment required to create short supply chains, so relevant for the circular economy and the ecological transition.These transition areas need to be rethought as new collective spaces of the contemporary city, areas for the proliferation of biodiversity, inhibited from settlement increase and subject to restrictions on car traffic. In them, the circular dimension of the new green economy could give shape to certain spatial conditions and new landscapes.Two main spatial models can describe this sustainable reform of the peri-urban territories. The first one assumes the figure of the “cluster”: a territorially and functionally defined region with one or more reference centres and an edge marking the discontinuity from other clusters. The second model is based on the figure of the “grid”: an unlimited mesh, which gives measure and organizes space according to a replicable and open system. This spatiality is built on a redundant and weak infrastructure, devoid of hierarchy, which can give rise to a sponge rich in pores, with neither internal nor external boundaries.The concept of the materiality also deals with the physical status of each context where the clusters of shortening flows would define local metabolisms, self-sufficient, marked by the use and recycling of what can be produced or “extracted” in the cluster itself. The closing of short supply chains for the use and recycling of materials, also with reference to the construction cycle and CDW recycling, would have direct consequences on the architectural character of the new arrangements: a kind of hyper-contextualism in which the landscape takes on grains, colours, materiality, closely linked to the local condition.Finally, a reflection on the rationales of the project is outlined. What is proposed, in fact, requires going beyond the traditional way in which the project has been conceived. In fact, these urban reconfiguration processes, structurally open to uncertainty, would take advantage of a programmatic choice of spatial incompleteness: a condition of “unfinished”, open to the accumulation over time of functions, forms, aggregations and densifications.

Abstract:
This chapter studies neighbourhood choice and satisfaction, more specifically what attracts people to diverse and deprived urban areas, and how perceptions of local diversity play a role in this. The importance of diversity for neighbourhood choice and satisfaction has hardly been studied among non-middle-class residents. The chapter then presents a qualitative study of neighbourhood choice and satisfaction among residents of different social classes in highly diverse and disadvantaged neighbourhoods in Antwerp (Belgium) and Rotterdam (the Netherlands). The primary motive for choosing to live in a diverse neighbourhood is the availability of affordable housing. For poor residents and migrants, the presence of family and friends in the neighbourhood is also an important motive. Only for some interviewees, mostly of minority ethnic backgrounds, neighbourhood ethnic diversity is an important factor for their neighbourhood choice, mainly because they prefer to live in neighbourhoods that are not dominated by a majority group.

Abstract:
While baseline testing may be appropriate in some endocrine disorders (e.g. hyper/hypothyroidism), many hormones are not secreted in a constant fashion (e.g. pulsatile (growth hormone), diurnal (cortisol)), and are also age (IGF-1) and pubertal stage (Luteinizing hormone/follicle-stimulating hormone/testosterone/oestradiol) dependent. In these circumstances, stimulation (or suppression) testing including using hypothalamic/pituitary hormones may be required. Testing can either be performed to identify occult endocrine dysfunction in high-risk groups, or alternatively to confirm (or exclude) endocrine disorders in conjunction with careful clinical assessment. These tests are, however, often complex and difficult to perform, with both false-positive and false-negative results, so careful and appropriate timing and choice of tests is required to ensure optimal outcomes.

Abstract:
Quaternion Encryption Scheme (QES) is shown to be susceptible to the Known Plaintext-Ciphertext Attack (KPCA) due to improper choice of frame size and the procedure of secret quaternion updating. In this chapter, the authors propose a modification of the QES (M-QES) that is resistant to the KPCA. The M-QES is based on adjusting the frame size and the quaternion update procedure. An approach for effective hardware implementation of the proposed algorithm, HW-QES, is discussed. The HW-QES uses addition and shift operations. Extension of quaternion approach to another hyper-complex number systems, octonions, is used for designing a new hardware-oriented encryption algorithm, HW-OES. Experimental results show that the proposed M-QES and HW-QES are six-eight times more effective in the encryption quality of signals than the original QES. Additionally, M-QES and HW-OES are shown to be significantly more effective in the encryption quality of images than the original QES and well-known AES. The results show that the performance of the HW-QES is only 10% worse than that of QES.

This chapter presents the exploding numbers and broadening capacities of students and professors that skyrocket over time, especially as the hyper-modern society assembles around the university-based knowledge system. It discusses how schooling is seen as relevant for more and more sorts of people and points out how the dimensions of people are activated and incorporated. It also looks at people that are involved and seen not simply as passive entrants but as executors of ever more legitimate interests and capacities that is above all the general capacity for empowered choice or actorhood. The chapter describes the properly schooled person that is imagined to be a dramatic social actor, fit to master and change the world and not simply to be a carrier of received culture. It applies a neo-institutional perspective to the expansion of the university populations of reconstructed individual people.

The main task of the text is to characterize the harmony of strategy, tactics and operations of transformations as a single complex, opportunities and threats for it, predetermining the optimization of the organizational and managerial choice. The applied methods are based on the unity of historical and logical, analysis and synthesis. A feature of the elaboration is the consideration of the development of a managerial decision as a process of co-creation. To optimize its result, the author analysed the opportunities and threats from the point of view an objective and subjective, fundamental and relevant nature. The decisive differences in the conditions and environment for the realizing of organizational and managerial selection are highlighted, in particular, the period of forced transformations of the post-global transition. The role of hyper-industrialization in the transition to accomplishing of constant modernization is shown. The place of the social environment, Super-project and development clusters for stimulating the desired transformations is characterized. The potential of a flexible balance of strategy, tactics and operational art in the combination of the possibilities of national and regional government and local self-management in the carrying out of reflexive transformations has been revealed.

Solid Tungsten carbide plungers are the primary choice for hyper compressors for manufacturing Low Density Polyethylene (LDPE.) However, tungsten carbide plungers in this severe service is susceptible to premature failures and/or short runs due to gas leakage from the running combinations of lubrication, packing and plunger surface. Thermal fatigue (heat checking), fretting, corrosion and scoring are common problems found on the plunger surface resulting in premature leakage or even plunger breakage. This paper elaborates on these plunger problems, repairs and possible reasons for these surface defects.

Abstract:
In this paper we report on new experiments of Hyper-Rayleigh Scattering (HRS) in solution, i.e. incoherent second harmonic light scattered from solutions illuminated by intense (IR) laser pulses. The HRS-technique, developed recently1, allows an accurate and easy determination of first order hyperpolarisabilities β of molecules. The great advantage of HRS as compared to electric field induced second harmonic generation (EFISHG, the other technique to determine β) is the absence of an orienting electric field to reduce the intrinsic symmetry of an isotropic solution. As a consequence data on the dipole moments are not needed and local field correction factors are unnecessary. HRS allows the determination of β of ionic species and will be the method of choice for the investigation of apolar molecules where p originates from octopolar charge distributions.2

Abstract:
This study describes the development of a multi-body foot contact model consisting of spherical volumetric models for the surfaces of the foot. The developed model is two-dimensional, and consists of two segments, the hind-foot, mid-foot, and forefoot as one rigid body and the phalanges collectively as the second rigid body. The model has four degrees of freedom: ankle x, y, hind-foot orientation, and metatarsal joint angle. Both ankle and metatarsal joints are assumed to be revolute joints. Three different types of contact elements are targeted: Kelvin-Voigt, linear volumetric, and nonlinear volumetric. The models are kinematically driven at the ankle and the metatarsal joints, and simulated horizontal and vertical ground reaction forces as well as center of pressure location are compared against the measured quantities within a complete human gait cycle. The hyper-volumetric foot contact model was found to be a suitable choice for foot/ground interaction modelling within human gait simulations.

Abstract:
Booster, Primary and Hyper compressors are the pieces of machinery used to reach the extremely high pressures needed for the reaction in Low-Density Polyethylene plants. Wide operating ranges are necessary due to the different products and conditions required by the process to obtain both homo and co-polymers required by the market. A suitable capacity control system has to be studied during the design phase to optimize the operation particularly for Booster and Primary compressors, that are supplying the required flow to the Hyper, then compressed to the reactor. In the latter the traditional capacity control cannot be used because of the very high pressures involved and for start-up and various preparation activities the by-pass along the reactor is the only flow regulation possibility. On the contrary, in Booster and Primary there is a wider choice of CCS, from “clearance pockets” to “variable speed drive”, from step to step-less. This paper gives a brief overview of these systems, explains their pros and cons and examines the impact they have on valve behaviour explaining the CCS-valve interactions. In particular it focuses on the new generation of electro-mechanical step-less control systems.
