description: The numbers of senior citizens are increasing tremendously in Malaysia, so the demand for retirement homes is significant to accomplish for this group. Hence, are Malaysians prepared to face the challenges of an ageing nation, and are our citizens ready for retirement? In Malaysia generally, the concept of retirement home can be classified into resort-style homes, luxury residential and villa, villages or orchard with Greenery Park, nursing or primary care base, Social and community care, rehabilitation and curative centre and basic home care. This paper will classified the facilities and services of the retirement home according to amenities and location base, special and dedicated treatment, long term home care similar to Palliative and Hospice and basic personal care. The hierarchy of needs of an elderly will then be classified into First Tier labelled as (1-F) provides luxury and exclusive requirement with advanced facilities and services provided (2-F) provides Instrumental Activities and Daily Living (IADL), luxury amenities, club base and places for holiday up, dedicated security and surveillance and specialist clinic; Second Tier labelled as (1-S) will provide centre-based care including all accommodation and services. (2S) provides amenities, security and surveillance (3-S) provide transport services, housekeeping and laundry services and finally Basic Needs as Third Tiers labelled as (1-T) provides personal care and grooming services until Instrumental activities of daily living (IADL) up to (7T) provides transport services, housekeeping and laundry services. The Hierarchy of Needs for an elderly not only in home care but also in their own home requires a varieties provision of care as mentioned above. This paper will forward retirement concepts adopted in Malaysia, and other countries. A proposed new retirement concepts, which might be ideal for Malaysian context will be forwarded at the end of this paper.

description: Conditional dynamics due to continuous optical measurements has successfully been applied for state reconstruction and feedback cooling in optomechanical systems. In this article, we show that the same measurement techniques can be used to unravel nonclassicality in optomechanical limit cycles. In contrast to unconditional dynamics, our approach gives rise to nonclassical limit cycles even in the sideband-unresolved regime, where the cavity decay rate exceeds the mechanical frequency. We predict a significant reduction of the mechanical amplitude fluctuations for realistic experimental parameters.

description: We consider localization of a random walk (RW) when attracted or repelled by multiple extended manifolds of different dimensionalities. In particular, we focus on $(d-1)$- and $(d-2)$-dimensional manifolds in $d$-dimensional space, where attractive interactions are (fully or marginally) relevant. The RW can then be in one of four phases where it is localized to neither, one, or both manifolds. The four phases merge at a special multi-critical point where (away from the manifolds) the RW spreads diffusively. Extensive numerical analyses on two dimensional RWs confined inside or outside a rectangular wedge confirm general features expected from a continuum theory, but also exhibit unexpected attributes, such as a reentrant localization to the corner while repelled by it.

The Multi-Dimensional Structure of Radiative Shocks: Suppressed Thermal X-rays and Relativistic Ion Acceleration

Publisher: name: arXiv
Year: 2018
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: Radiative shocks, behind which gas cools faster than the dynamical time, play a key role in many astrophysical transients, including classical novae and young supernovae interacting with circumstellar material. The dense layer behind high Mach number $\mathcal{M} \gg 1$ radiative shocks is susceptible to thin-shell instabilities, creating a "corrugated" shock interface. We present two and three-dimensional hydrodynamical simulations of optically-thin radiative shocks to study their thermal radiation and acceleration of non-thermal relativistic ions. We employ a moving-mesh code and a specialized numerical technique to eliminate artificial heat conduction across grid cells. The fraction of the shock's luminosity $L_{\rm tot}$ radiated at X-ray temperatures $kT_{\rm sh} \approx (3/16)μm_p v_{\rm sh}^{2}$ expected from a one-dimensional analysis is suppressed by a factor $L(>T_{\rm sh}/3)/L_{\rm tot} \approx 4.5/\mathcal{M}^{4/3}$ for $\mathcal{M} \approx 4-36$. This suppression results in part from weak shocks driven into under-pressured cold filaments by hot shocked gas, which sap thermal energy from the latter faster than it is radiated. Combining particle-in-cell simulation results for diffusive shock acceleration with the inclination angle distribution across the shock (relative to an upstream magnetic field in the shock plane$-$the expected geometry for transient outflows), we predict the efficiency and energy spectrum of ion acceleration. Though negligible acceleration is predicted for adiabatic shocks, the corrugated shock front enables local regions to satisfy the quasi-parallel magnetic field geometry required for efficient acceleration, resulting in an average acceleration efficiency of $ε_{\rm nth} \sim 0.005-0.02$ for $\mathcal{M} \approx 12-36$, in agreement with modeling of the gamma-ray nova ASASSN-16ma.

Fault-tolerant wide-area control of power systems
Creators: name: Segundo Sevilla, Felix Rafael
Publisher: name: Imperial College London
Year: 2013

description: In this thesis, the stability and performance of closed-loop systems following the loss of sensors or feedback signals (sensor faults) are studied. The objective is to guarantee stability in the face of sensor faults while optimising performance under nominal (no sensor fault) condition. One of the main contributions of this work is to deal effectively with the combinatorial binary nature of the problem when the number of sensors is large. Several fault-tolerant controller and observer architectures that are suitable for different applications are proposed and their effectiveness demonstrated. The problems are formulated in terms of the existence of feasible solutions to linear matrix inequalities. The formulations presented in this work are described in a general form and can be applied to a large class of systems. In particular, the use of fault-tolerant architectures for damping inter-area oscillations in power systems using wide-area signals has been demonstrated. As an extension of the proposed formulations, regional pole placement to enhance the damping of inter-area modes has been incorporated. The objective is to achieve specified damping ratios for the inter-area modes and maximise the closed-loop performance under nominal condition while guaranteeing stability for all possible combinations of sensors faults. The performances of the proposed fault-tolerant architectures are validated through extensive nonlinear simulations using a simplified equivalent model of the Nordic power system.

description: There are now about fifty known radio pulsars in binary systems, including at least five in double neutron star binaries. In some cases, the stellar masses can be directly determined from measurements of relativistic orbital effects. In others, only an indirect or statistical estimate of the masses is possible. We review the general problem of mass measurement in radio pulsar binaries, and critically discuss all current estimates of the masses of radio pulsars and their companions. We find that significant constraints exist on the masses of twenty-one radio pulsars, and on five neutron star companions of radio pulsars. All the measurements are consistent with a remarkably narrow underlying gaussian mass distribution, m = 1.35 +- 0.04 solar masses. There is no evidence that extensive mass accretion (delta m >~ 0.1 solar mass) has occurred in these systems. We also show that the observed inclinations of millisecond pulsar binaries are consistent with a random distribution, and thus find no evidence for either alignment or counteralignment of millisecond pulsar magnetic fields.

description: After reviewing the Green-Schwarz superstring using the approach of Siegel, the superstring is covariantly quantized by constructing a BRST operator from the fermionic constraints and a bosonic pure spinor ghost variable. Physical massless vertex operators are constructed and, for the first time, N-point tree amplitudes are computed in a manifestly ten-dimensional super-Poincaré covariant manner. Quantization can be generalized to curved supergravity backgrounds and the vertex operator for fluctuations around $AdS_5\times S^5$ is explicitly constructed. This review is written in a self-contained manner and is based on talks given at the Fradkin Memorial Conference and Strings 2000.

Adaptation strategies for self-organising electronic institutions
Creators: name: Sanderson, David William
Publisher: name: Imperial College London
Year: 2013

description: For large-scale systems and networks embedded in highly dynamic, volatile, and unpredictable environments, self-adaptive and self-organising (SASO) algorithms have been proposed as solutions to the problems introduced by this dynamism, volatility, and unpredictability. In open systems it cannot be guaranteed that an adaptive mechanism that works well in isolation will work well — or at all — in combination with others. In complexity science the emergence of systemic, or macro-level, properties from individual, or micro-level, interactions is addressed through mathematical modelling and simulation. Intermediate meso-level structuration has been proposed as a method for controlling the macro-level system outcomes, through the study of how the application of certain policies, or norms, can affect adaptation and organisation at various levels of the system. In this context, this thesis describes the specification and implementation of an adaptive affective anticipatory agent model for the individual micro level, and a self-organising distributed institutional consensus algorithm for the group meso level. Situated in an intelligent transportation system, the agent model represents an adaptive decision-making system for safe driving, and the consensus algorithm allows the vehicles to self-organise agreement on values necessary for the maintenance of “platoons” of vehicles travelling down a motorway. Experiments were performed using each mechanism in isolation to demonstrate its effectiveness. A computational testbed has been built on a multi-agent simulator to examine the interaction between the two given adaptation mechanisms. Experiments involving various differing combinations of the mechanisms are performed, and the effect of these combinations on the macro-level system properties is measured. Both beneficial and pernicious interactions are observed; the experimental results are analysed in an attempt to understand these interactions. The analysis is performed through a formalism which enables the causes for the various interactions to be understood. The formalism takes into account the methods by which the SASO mechanisms are composed, at what level of the system they operate, on which parts of the system they operate, and how they interact with the population of the system. It is suggested that this formalism could serve as the starting point for an analytic method and experimental tools for a future systems theory of adaptation.

The wavelengths, precise to a level ~ 50-150 m/s, are given for both flux and disc-centre spectra, as measured in relatively recent FTS solar atlases. This catalogue modernizes existing sources based on photographic measurements and provides a benchmark to test and perform wavelength calibrations of astronomical spectra. It will also permit observers to improve the absolute wavelength calibration of solar optical spectra when lamps are not available at the telescope.

description: We report the discovery of the hottest hybrid B--type pulsator, KIC\,3240411, that exhibits the period spacing in the low--frequency range. This pattern is associated with asymptotic properties of high-order gravity (g) modes. Our seismic modelling made simultaneously with the mode identification shows that dipole axisymmetric modes best fit the observations. Evolutionary models are computed with MESA code and pulsational models with the linear non-adiabatic code employing the traditional approximation to include the effects of rotation. The problem of mode excitation is discussed. We confirm that significant modification is indispensable to explain an instability of both pressure and gravity modes in the observed frequency ranges of KIC\,3240411.

Super-Eddington winds from Type I X-ray bursts

Year: 2018
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We present hydrodynamic simulations of spherically symmetric super-Eddington winds from radius-expansion type I X-ray bursts. Previous studies assumed a steady-state wind and treated the mass-loss rate as a free parameter. Using MESA, we follow the multi-zone time-dependent burning, the convective and radiative heating of the atmosphere during the burst rise, and the launch and evolution of the optically thick radiation-driven wind as the photosphere expands outward to radii $r_{\rm ph} \gtrsim 100\text{ km}$. We focus on neutron stars (NSs) accreting pure helium and study bursts over a range of ignition depths. We find that the wind ejects $\approx 0.2\%$ of the accreted layer, nearly independent of ignition depth. This implies that $\approx 30\%$ of the nuclear energy release is used to unbind matter from the NS surface. We show that ashes of nuclear burning are ejected in the wind and dominate the wind composition for bursts that ignite at column depths $\gtrsim 10^9\text{ g cm}^{-2}$. The ejecta are composed primarily of elements with mass numbers $A> 40$, which we find should imprint photoionization edges on the burst spectra. Evidence of heavy-element edges has been reported in the spectra of strong, radius-expansion bursts. We find that after $\approx 1\text{ s}$ the wind composition transitions from mostly light elements ($^4$He and $^{12}$C), which sit at the top of the atmosphere, to mostly heavy elements ($A>40$), which sit deeper down. This may explain why the photospheric radii of all superexpansion bursts show a transition after $\approx 1\text{ s}$ from a superexpansion ($r_{\rm ph}>10^3\text{ km}$) to a moderate expansion ($r_{\rm ph}\sim 50\text{ km}$).

Assessment of pain and its treatment in neonates
Creators: name: Kariholu, Ujwal
Publisher: name: Imperial College London
Year: 2013

description: Babies on the neonatal unit are often exposed to a number of noxious stimuli. Procedures such as venepuncture, insertion of cannulae, heel prick and endotracheal ventilation can occur on a daily basis, and the majority of these babies do not receive any pain relief treatment. Current methods of assessing pain in neonates, comprising behavioural cues and physiological markers, can be difficult to relate directly to pain perception, especially in preterm infants, as they can also be indicative of other states such as stress, anxiety and hunger. Accurate recognition of pain in a neonate could enable more appropriate use of analgesics, thereby reducing morbidity and limiting potential side-effects. We investigated 48 babies using techniques that may evaluate the function of nociceptor-specific nerve fibres and central pain pathways, in comparison with currently used behavioural and physiological indicators. These techniques included “objective” physiological responses to procedural pain, such as skin axon-reflex vasodilatation (flare) responses, and novel contact cerebral evoked potentials in response to warm (non-painful) stimuli. We recorded physiological responses (i.e. sweat rate, changes in blood flow, sympathetic skin response) during clinically required heel prick procedures in babies on the neonatal unit. Palmar sweat rate was higher in babies ≥ 36 weeks, and significantly correlated with gestational age. We did not see any relationship between the painful heel prick procedure and palmar sweat response. We were unable to demonstrate any increase in the sympathetic skin response waveforms post-heel prick procedure in the one baby we studied. Changes in local skin blood flow around the heel prick (ipsi-lateral limb) and in the opposite foot (contralateral limb) were very variable, although many babies showed an increase in the blood flow post-heel prick. We also performed a behavioural analysis (using PIPP) during heel prick procedures in babies whilst simultaneously recording their palmar sweat levels. We could not demonstrate any definite association between the palmar sweat response to pain and the PIPP scores. The feasibility of recording warm temperature induced cerebral evoked potentials in neonates was investigated, using scalp EEG electrodes, in response to a cutaneous stimulus with a thermode destination temperature 37°C. However, the EEG waveforms were obscured by ocular artefact, and thus warm temperature evoked potentials could not be demonstrated in neonates, unlike adults. In conclusion, current methods of behavioural and physiological assessment of pain in neonates have an important role, but are not specific and unlikely to be helpful in monitoring the effects of new analgesics. Warm stimuli evoked cerebral potentials are technically difficult to record in neonates, and heat pain stimuli are unjustified, but other techniques such as functional MRI may provide a useful measure and deserve study. The assessment and treatment of pain in neonates remains a major unmet clinical need.
On the DLCQ as a light-like limit in string theory

description: We study the issue of defining the discrete light-cone quantization (DLCQ) in perturbative string theory as a light-like limit. While this limit is unproblematic at the classical level, it is non-trivial at the quantum level due to the divergences by the zero-mode loops. We reconsider this problem in bosonic string theory. We construct the multi-loop scattering amplitudes in both open and closed string theories by using the method of Kikkawa, Sakita and Virasoro (KSV), and then we show that these scattering amplitudes are perfectly well-defined in this limit. We also discuss the vacuum amplitudes of the string theory. They are, however, ill-defined in the light-like limit due to the zero-mode loop divergences, and hence we want supersymmetry to cure those pathological divergences even in string theory.

Lubrication and tribological performance optimizations for micro-electro-mechanical systems
Creators: name: Leong, Jonathan Yonghui
Publisher: name: Imperial College London
Year: 2012

description: Lubricants and lubrication have been of great interest to mankind since the introduction of machines with sliding/rolling surfaces into everyday life. With the recent trend of miniaturization, Micro-Electro-Mechanical Systems (MEMS) have taken centre stage, featuring components with scales in dimensions as small as nanometres. In this PhD study, two approaches to solving MEMS tribology problems have been pursued. First, a novel direct lubrication method using well-known lubricants such as perfluoropolyether (PFPE) and multiply alkylated cyclopentane (MAC) was developed and tested using reciprocating sliding and actual MEMS tribometry. The second approach utilized the concept of hydrodynamic lubrication and selective surface modification for MEMS. To combat spreading and starvation of lubricants in small contacts such as in MEMS, selective modification of the silicon surface with hydrophobic (non-wetting) and hydrophilic (wetting) portions was carried out and found to increase the force required to move a droplet of lubricant from a designated location on the surface. Octadecylamine and dodecylamine were also used as additives to successfully induce autophobicity in hexadecane, and the various spreading behaviours investigated. In conclusion, several new approaches to tackling tribological problems in MEMS have been researched. These methods are easily adapted to suitable MEMS devices and greatly reduce adhesion and friction, and increase wear and device life by several orders of magnitude.
Impacts of traffic interventions on road safety : an application of causal models
Creators: name: Li, Haojie
Publisher: name: Imperial College London
Year: 2013

description: This thesis is concerned with the causal relationship between traffic interventions and road safety. It focuses on two issues that have been overlooked in the existing empirical literature: the establishment of a causal link between traffic interventions and road traffic accidents, and the application and development of formal causal approaches, which have not yet been applied in the field of road safety. In the past decades substantial studies have been conducted to investigate the risk factors contributing to road accidents. It has been shown that the frequency and severity of road accidents are associated with various factors, including traffic characteristics, road environment and demographic characteristics. However, the existence of a causal link between traffic interventions and road accidents remains unclear due to the complex character of traffic interventions. Meanwhile, the lack of formal causal models makes it difficult fully to address issues such as confounding effects and regression to the mean bias. This thesis begins by reviewing and discussing different types of traffic interventions in order to demonstrate the chains through which traffic interventions are related to road safety. To address the shortcomings in empirical literature, three models for causal inferences are discussed: the difference-in-difference method, the propensity score matching method and Bayesian methods. These formal causal approaches are then applied to three empirical studies: the London congestion charging scheme, speed limit enforcement cameras, and the road network design. The conventional models are also employed and compared with formal causal models.

description: We present an analysis on the production of two same-sign lepton pairs at the LHC, mediated by bileptons in the $SU(3)_c\times SU(3)_L\times U(1)_X$ theory, the so-called 331 model. Compared to other 331 scenarios, in this model the embedding of the hypercharge is obtained with the addition of 3 exotic quarks and doubly-charged vector gauge bosons with lepton numbers $\pm 2$ in the spectrum ($Y^{\pm\pm}$), which can mediate the production of four-lepton final states. Furthermore, a complete description of the model requires the introduction of a Higgs scalar sector, which is a sextet of $SU(3)_L$, necessary in order to correctly account for the lepton masses. As a result of this, new doubly-charged scalar states $H^{\pm\pm}$ are part of the spectrum as well and can in principle compete with the vector bileptons in giving rise to four-lepton final states. We investigate both channels and study several observables at the LHC, for both signal and Standard Model $ZZ$ background. With respect to previous work on vector- and scalar-bilepton production, we use the most updated exclusion limits at the LHC and implement the 331 model in a full Monte Carlo simulation code, capable of being interfaced with any analysis framework. Our result is that the 331 signal can be discriminated from the background with a significance of 6-9 standard deviations, depending on the LHC luminosity, with the vector bileptons dominating over the scalar ones.

Slow, cold beams of polar molecules for precision measurements
Creators: name: Bulleid, Nicholas Edward
Publisher: name: Imperial College London
Year: 2013

description: This thesis reports on the use of buffer gas cooling to produce slow and intense molecular beams, with the aim of creating a source of molecules that can be used to measure the electron electric dipole moment. A beam of Yb is extracted from a buffer gas cell by entrainment in a flow of helium. The beam is characterised and simulations are performed of the helium flow through the cell to better understand the effect this has on the beam characteristics. The velocity of the beam is found to vary between 65 m/s[superscript -1] and 204 m/s[superscript -1] depending on the helium flow through the cell, in agreement with the predictions of the simulations. The temperature of the beam is 2.4 K and the minimum divergence is 12°. The percentage of Yb that is extracted from the cell is ~10%. Sources which use a pulsed valve to produce a supersonic jet are also characterised at cryogenic temperatures. The addition of a thermalisation cell is found to produce beams that are slower, colder and more intense. The peak beam intensity is 4.5×10[superscript 10] molecules per seradian per pulse, the velocity (206 ± 5) m/s and the translational temperature is (12.3 ± 0.5) K. An electric decelerator is used to decelerate a pulse of YbF molecules from 300 m/s[superscript -1] to 276 m/s[superscript -1] by confining them to a travelling trap. Simulations of the molecules in the decelerator show that its acceptance is greater than those demonstrated previously. A detailed understanding of this deceleration is developed. The Franck-Condon factors for the A[superscript 2]Π[subscript 1/2] (v = 0) − X[superscript 2]Σ[superscript +] (v - 0, 1, 2) transition of YbF are measured. The results show that, using three lasers, the molecule could be laser-cooled.
Inflammation in pulmonary arterial hypertension : NF-kappa B signalling and the role of corticosteroids
Creators: name: Price, Laura
Publisher: name: Imperial College London

description: Pulmonary arterial hypertension (PAH) is a severe disease with limited therapeutic options characterised by proliferation of vascular cells, which in part relates to the presence of increased inflammation. I hypothesised that the inflammatory transcription factor NF-­kappa B (NF-­κB) was activated in human idiopathic PAH (iPAH), and that inhibition of NF­‐κB using the synthetic glucocorticoid (GC) dexamethasone would reverse pulmonary hypertension (PH) and inflammation in the rat monocrotaline (MCT) model; in rat and human pulmonary arterial smooth muscle cells (PASMC); and in human peripheral blood mononuclear cells (PBMC). Activation of NF-­κB was demonstrated in pulmonary macrophages, lymphocytes, pulmonary endothelial cells (EC) and PASMC in patients with severe iPAH, and in the rat MCT model. Dexamethasone reversed PH and improved survival in MCT-­induced PH in rats, with a reduction in interleukin (IL)-­6 expression, and a reduction in vascular cell NF­‐κB activation. Pulmonary BMPR­‐II mRNA expression was also low in rats with MCT-­PH; this was increased following dexamethasone treatment. The dexamethasone‐induced reduction in rat vessel medial thickness was related to both a reduction in serum-stimulated rat PASMC proliferation, and also increased PASMC apoptosis. I then demonstrated that dexamethasone inhibited lipopolysaccharide (LPS)-­ and TNF-­α-induced IL-­6 and CXCL8 release in an NF-­‐κB-­‐dependent manner in control human PASMC, whole blood and PBMC assays. When stimulated with these activators of NF-­κB, PBMC from PAH patients were relatively hyporesponsive compared to control cells in terms of IL-­6 and CXCL8 release, and were less responsive i.e. more resistant to dexamethasone‐induced suppression of cytokine release compared to controls. NF-­κB activation is marked in patients with end-­stage iPAH, and reversal of NF-­‐κB activation and PH is possible in the MCT-induced PH model. Whether inflammation might be a therapeutic target in human PAH -­ and whether PAH is a clinically GC-­sensitive or GC-resistant condition -­ requires further exploration.

description: The computational effort in the calculation of Wilson fermion quark propagators in Lattice Quantum Chromodynamics can be considerably reduced by exploiting the Wilson fermion matrix structure in inversion algorithms based on the non-symmetric Lanczos process. We consider two such methods: QMR (quasi minimal residual) and BCG (biconjugate gradients). Based on the decomposition $M/κ={\bf 1}/κ-D$ of the Wilson mass matrix, using QMR, one can carry out inversions on a {\em whole} trajectory of masses simultaneously, merely at the computational expense of a single propagator computation. In other words, one has to compute the propagator corresponding to the lightest mass only, while all the heavier masses are given for free, at the price of extra storage. Moreover, the symmetry $γ_5\, M= M^{\dagger}\,γ_5$ can be used to cut the computational effort in QMR and BCG by a factor of two. We show that both methods then become---in the critical regime of small quark masses---competitive to BiCGStab and significantly better than the standard MR method, with optimal relaxation factor, and CG as applied to the normal equations.

description: Land types visually reflect the comprehensive attributes of land resources, allowing the monitoring of land development dynamics and evaluation of the land use situation. However, existing land type classification systems in urban areas lacked the integrated consideration of human characteristics and natural landscapes. Thus, this study integrated multi-source geospatial data including Weibo check-in, taxi-tracking, building-surveys, and remote sensing images to acquire anthropogenic features including building characteristics and human activities, and natural landscape features including water, vegetation, and urban vacant land. Three-level urban land type classification system was then constructed with two primary categories, six secondary categories, and 17 tertiary categories to reveal integrated characteristics of urban land resources. Based on the extracted urban areas of Shenzhen, urban land types in 2014 were mapped at street block to reveal the distribution and utilization efficiency of land resources in a visual and detailed format, thus guiding land resources optimization.

description: Using the Chern-Simon formulation of (2+1) gravity, we derive, for the general asymptotic metrics given by the Fefferman-Graham-Lee theorems, the emergence of the Liouville mode associated to the boundary degrees of freedom of (2+1) dimensional anti de Sitter geometries. Holonomies are described through multi-valued gauge and Liouville fields and are found to algebraically couple the fields defined on the disconnected components of spatial infinity. In the case of flat boundary metrics, explicit expressions are obtained for the fields and holonomies. We also show the link between the variation under diffeomorphisms of the Einstein theory of gravitation and the Weyl anomaly of the conformal theory at infinity.

Effects based stimulation of ideas in design and engineering

description: The landmark date that modern researchers started to focus on creativity relates to J. P. Guiford’s 1950 address to the American Psychological Association. From then on, investigations mainly focused on individual’s personality traits to identify their associations with creativity. In recent decades, social factors have gradually been defined as playing a crucial role in creativity. The main four factors on the performance of creative thinking process are: motivation, expertise, sponsorship, and communication skills. The creativity engine is a model that uses the analogy of a combustion engine with inputs (four factors) and creative outputs. The short term memory is refreshed in order to retain information while also supplying cues to enable the effective search of long term memory where solutions reside. In modern design processes, designers often face a design task that relates to fields they are relatively unfamiliar with and the knowledge accumulation they have (long term memory) is not specific to the design task. To compensate for this shortage, an effects database system named “Effect Genius” has been developed and implemented to provide problem related effects and principles to assist designers rapidly access to knowledge guidance from experts at any stage of the design process. A web information gathering and analysis function is also implemented to update the data in the Effects Genius and identify new proposed effects from published data sources. Two case studies were explored to evaluate the effectiveness and efficiency of the Effects Genius system in the idea generation process, which has three steps (keyword conclusion, related effects analysis, and idea generation). Some users also provided feedback on their usages of the system. The comprehensive performance of the example ideas in the two case studies and positive feedback from other users demonstrate that the data gathered by the information gathering system have potential benefits for design tasks and the Effects Genius system indeed stimulates the idea generation process by suggesting design-related effects.
