description: $\DeclareMathOperator{\poly}{poly}$In the classic polyline simplification problem, given a polygonal curve~$P$ consisting of $n$ vertices and an error threshold $\delta \geq 0$, we want to replace $P$ by a subsequence~$Q$ of minimal size such that the distance between the polygonal curves $P$ and $Q$ is at most $\delta$. The distance between curves is usually measured using the Hausdorff or continuous Fréchet distance. These distance measures can be applied globally, i.e., to the whole curves $P$ and $Q$, or locally, i.e., to each simplified subcurve and the line segment that it was replaced with separately (and then taking the maximum). This gives rise to four problem variants: Global-Hausdorff simplification (known to be NP-hard), Local-Hausdorff simplification (can be solved in time $O(n^3)$), Global-Fréchet simplification (can be solved in time $O(k n^5)$, where $k$ is the size of the optimum simplification), and Local-Fr\'{e}chet simplification (can be solved in time $O(n^3)$). Our contribution is as follows: • Cubic time for all variants:\ For Global-Fréchet simplification, we design an algorithm running in time $O(n^3)$. This shows that all three problems (Local-Hausdorff, Local-Fréchet, and Global-Fréchet) can be solved in cubic time. All these algorithms work over a general metric space such as $(\mathbb{R}^d,L_p)$, but the hidden constant depends on $p$ and (linearly) on~$d$. • Cubic conditional lower bound: We provide evidence that in high dimensions, cubic time is essentially optimal for all three problems (Local-Hausdorff, Local-Fréchet, and Global-Fréchet). Specifically, improving the cubic time to $O(n^{3-\epsilon} \poly(d))$ for polyline simplification over $(\mathbb{R}^d,L_p)$ for $p = 1$ would violate plausible conjectures. We obtain similar results for all $p \in [1,\infty), p \ne 2$. In total, in high dimensions and over general $L_p$-norms we resolve the complexity of polyline simplification with respect to Local-Hausdorff, Local-Fréchet, and Global-Fréchet, by a providing new algorithm and conditional lower bounds.

description: The shapes of cell membranes are largely regulated by membrane associated, curvature active, proteins. We use a numerical model of the membrane with elongated membrane inclusions, recently developed by us, which posses spontaneous directional curvatures that could be different along and perpendicular to its long axis. We show that, due to membrane mediated interactions these curvature inducing membrane nematogens can oligomerize spontaneously, even at low concentrations, and change the local shape of the membrane. We demonstrate that for a large group of such inclusions, where the two spontaneous curvatures have equal sign, the tubular conformation and sometime the sheet conformation of the membrane are the common equilibrium shapes. We elucidate the factors necessary for the formation of these {\it protein lattices}. Furthermore, the elastic properties of the tubes, like their compressional stiffness and persistence length are calculated. Finally, we discuss the possible role of nematic disclination in capping and branching of the tubular membranes.

description: It is indeed a matter of great significance for system engineers and scientists to derive new classes of lifetime distributions for providing a better statistical model which will fit a given lifetime data set. It is known that many real time data have varied characteristics and can be modeled by distributions with bathtub and upside down bathtub failure rates viz., Weibull, Modified Weibull, Inverse Weibull. This paper proposes a method which generates a family of distributions having bathtub (BT)-shaped failure rate from a distribution having upside down bathtub (UBT)-shaped failure rate and vice-versa. The proposed method is validated with the help of a few statistical distributions. The closure properties of the proposed model under various reliability operations are studied.

description: During the development of software and electronic devices, it is inevitable to make mistakes. In large, developed companies, assigning a request to the right development team or even a department is not an easy task. Often, the creation of software bug reports and assignment to groups is also formalized by appropriate processes. The paper presents a novel method of software bug report assignment to a group of developers or analysts. A specific usage of organizational structure at the company is a key component of the proposed approach. There are presented results from real use application including both machine learning predictions and human decisions. Human predictions are not independent, the issues are raised as to why comparing the results of machine learning models with those of humans may be inappropriate and what factors influence human decisions. The work also covers conclusive research about potential benefits of the application of automated assignment of bug reports.

description: Dieser Beitrag beschäftigte sich mit der Beeinflussung von nichtlinearen Komponenten in Schirmgehäusen. Mit Hilfe von S-Parameter Messungen einer Diodenleitung in eimem Rechteckresonator konnte gezeigt werden, wie diese, im Gegensatz zu einer linearen Leitung, auf Leistungsvariationen mit unterschiedlichem Resonanzverhalten reagiert. Bei einer Spektrumsanalyse der Leitung und Beaufschlagung des Resonators mit zwei hochfrequenten Signalen konnte gezeigt werden, wie die Einkopplung der beiden Signale auf die Nichtlinearität auch Störungen weit unterhalb der Frequenzen möglicher Einkoppelpfade hervorbringt. Fortsetzende Untersuchungen werden sich mit dem genauen Verlauf der Amplitude der Mischfrequenzen befassen um die Hypothese der Stärke der Mischprodukte rückführend auf die Stärke der Einkopplung der hochfrequenten Signale zu stützen. Weiterhin sollen weitere Leitungsvariationen mit z.B. einer mit Diode abgeschlossenen Leitung messtechnsich untersucht werden um sie mit analytischen Ergebnissen zu vergleichen.

Dafür wurden Hertzsche Dipole auf einer Kugeloberfläche verteilt und das Feld auf einem Ring, einer Zylinderoberfläche und einer Kugeloberfläche berechnet. Der Einfluss der elektrischen Größe, der Anzahl an Quellen und der Abtastrate wurde diskutiert. Wir haben die Gammaverteilung als passende Verteilungsfunktion vorgeschlagen und gezeigt wie simulierte und analytische Ergebnisse übereinstimmen. Mit Hilfe der Verteilungen können Konfidenzintervalle bei Umrechnung von Freifeldmessung, Voll- und Halbabsorberkammer Messergebnissen zu solchen von Modenverwirbelungskammer und Gigahertz Transversal ElektroMagnetisch-Zelle bzw. umgekehrt angegeben werden.

description: The aim of this work is to study the effects of environment on the growth in size of galaxies. We examine the stellar mass-size relation for a sample of isolated galaxies interpreted as stellar systems where evolution has been mainly governed by internal processes. Effects of environment on the stellar mass-size relation are evaluated by comparing our results with samples of less isolated early- and late-type galaxies, as well as, for the first time, different spiral subtypes. We find no difference in the stellar mass-size relation for very isolated and less isolated early-type galaxies. We find that late-type isolated galaxies are ~1.2 times larger than less isolated objects with similar mass. Isolated galaxies and comparison samples were divided into 6 morphological ranges (E/S0, Spirals, Sb, Sbc, Sc, and Scd-Sdm) and 5 stellar mass bins between log(M*)=[9,11.5]. In all cases the relation is better defined and has less scatter for the isolated galaxies. We find that as the morphological type becomes later the galaxy size (for a fixed stellar mass) becomes larger. For the lowest stellar mass bins log(M*)=[9,10] we find good agreement between sizes of AMIGA and comparison spirals. The isolated spiral galaxies in the high stellar mass bins log(M*)=[10,11] tend to be larger than less isolated galaxies. This difference in size is found for all spiral subtypes and becomes larger when we compare fully isolated galaxies with galaxies having 2 or more satellites (neighbors within 3 magnitudes of difference at a distance less than 250 kpc from the galaxy). Our results suggest that massive spiral galaxies located in low density environments, both in terms of major companions and satellites, have larger sizes than samples of less isolated galaxies. Hence the environment has played a role in the growth in size of massive spiral galaxies.

description: Üblicherweise werden bei der Ortung von Störquellen in ungerichteten Leitungsnetzwerken wie z.B. dem Stromnetz im Gegensatz zu Datennetzwerken, markante Merkmale von Störsignalen mit bekannten Mustern von typischen Störquellen verglichen und der vermutete Ort der Störquelle durch Korrelation des Ortes mit der Intensität der Merkmalsausprägung abgeleitet. Vielfach werden bei der Merkmalsgewinnung lineare Verfahren wie z.B. die Fouriertransformation oder solche der beschreibenden Statistik, wie z.B. Mittelwerte oder Varianzanalyse angewandt. Bei Störquellen, die sich im deterministischen Chaos befinden eignen sich nichtlineare Signalauswertungen besser. Bei der minimal-invasiven Methode zur Lokalisierung von Schaltnetzteilen mit schadhaftem Zwischenkreiskondensator in hochverfügbaren Anlagen kam z.B. die Methode der approximierten Entropie zum Einsatz.

description: Die ansteigende Anzahl der elektronischen Systeme im Fahrzeug und die Art der Anwendungen erhöhen den Bedarf an robusten Kommunikationssystemen. Im Hinblick auf echtzeitfähige Anwendungen in teilautomatisierten oder vollautomatisierten Fahrzeugen ergeben sich hohe Anforderungen an die notwendige Datenrate und die Übertragungssicherheit der Kfz-Kommunikationssysteme. Um diese Aufgabe zu erfüllen wurde als neues Kommunikationssystem Automotive Ethernet entwickelt [1], welches heute meist mit einer Übertragungsrate von 100 Mbit/s eingesetzt wird. Das Datensignal wird über eine ungeschirmte verdrillte Leitung übertragen und mithilfe einer Amplitudenmodulation, bestehend aus drei verschiedenen Spannungspegeln, codiert [2]. Die hohe Datenrate führt zu einer relativ geringen Symboldauer und die Verwendung von ungeschirmten Leitungen begünstigt die Einkopplung von Störungen, die zu einer Beeinträchtigung der Kommunikation führen können. Für den Entwurf von Kommunikationssystemen im Fahrzeug ist damit eine Bewertung der Kommunikationsgüte und die Beurteilung von potentiellen Störsignalen von hoher Bedeutung. Dieser Beitrag beschäftigt sich mit der Bewertung der Störfestigkeit einer 100BASE-T1 Kommunikation. Es werden verschiedene Ansätze zur Bewertung der Kommunikation diskutiert, um eine Aussage anhand der Signale auf dem Physical Layer vorzunehmen. Im Anschluss werden Untersuchungsergebnisse zur Störfestigkeit einer realen Kommunikationsstrecke gegenüber differentieller Störpulse vorgestellt. Die Untersuchungen zeigen den Einfluss verschiedener Störsignale auf Bit- und Paketfehler in einer 100BASE-T1 Kommunikation.

description: Hier wurde ein passives HHF-Filter vorgestellt, das Störspannungen im Netz eines Transformators im Bereich oberhalb von etwa 2kHz reduziert. Als eigentliche Störquellen sind Geräte der Leistungselektronik zu sehen. Funkentstörkondensatoren verstärken diese Störspannungen weil zusammen mit der Transformatorinduktivität ein Schwingkreis entsteht mit Resonanz im Bereich von etwa 2 bis 20kHz. Wie schon 1994 an einem 400kW-I-Umrichter festgestellt, kann man die Funkentstörkondensatoren nicht dauerhaft abklemmen um eine Anlage wieder funktionstüchtig zu machen. Wenn beispielsweise die Störspannung eine SPS-Steuerung außer Betrieb setzt und die gesamte Anlage stoppt, ist guter Rat teuer. Versuchsweise wurde ein dem HHF-Filter entsprechendes RC-Filter angeschlossen. Das beseitigte zwar nicht die Kommutierungseinbrüche, aber die Überschwingungen zu Beginn und am Ende der Kommutierungen und ermöglichte so einen ungestörten Betrieb. HHF-Filter der Firma Danfoss sind ohne Umschaltungen universell für Frequenzumrichter ohne und mit aktiven Gleichrichtern einsetzbar. Die Stückzahl der verkauften HHF-Filter ist noch überschaubar und es wird auch keineswegs zu jedem größeren Umrichter gleich ein HHF-Filter mitgeliefert. Erst wenn man bei Messungen Störpegelüberschreitungen bemerkt oder wenn Betriebsstörungen auftreten, kann man ohne viel Aufwand im Nachhinein ein HHF-Filter irgendwo an die Sammelschiene anschließen. Wenn ein Filter nicht reicht oder wenn es im HHF zur Stromüberlastung kommt, kann man einfach ein weiteres Filter parallel dazu anschließen.
Concept-based indexing in text information retrieval

description: Traditional information retrieval systems rely on keywords to index documents and queries. In such systems, documents are retrieved based on the number of shared keywords with the query. This lexical-focused retrieval leads to inaccurate and incomplete results when different keywords are used to describe the documents and queries. Semantic-focused retrieval approaches attempt to overcome this problem by relying on concepts rather than on keywords to indexing and retrieval. The goal is to retrieve documents that are semantically relevant to a given user query. This paper addresses this issue by proposing a solution at the indexing level. More precisely, we propose a novel approach for semantic indexing based on concepts identified from a linguistic resource. In particular, our approach relies on the joint use of WordNet and WordNetDomains lexical databases for concept identification. Furthermore, we propose a semantic-based concept weighting scheme that relies on a novel definition of concept centrality. The resulting system is evaluated on the TIME test collection. Experimental results show the effectiveness of our proposition over traditional IR approaches.

title: Determination of the Impact of a Human Capital Decision Cost Model on the Economic Performance Measures of a Technical Services Company
Creators: name: Temple, Jeffery A.
Publisher: name: Old Dominion University Libraries
Year: 2001

description: Human Capital has a major impact on cash flow management decisions in a Technical Services company. Decisions to hire or terminate employees to meet contract requirements affect the company's economic value. The objective of this research is to develop a model that assists management in establishing a starting point in making, as efficiently as possible, those decisions that impact employees' lives. To understand that impact, the operations and economic parameters of a Technical Services company are compared with those of a manufacturing company. This analysis establishes two · essential points for Technical Services organizations; first, that the capital investment decision is one of human capital skills and that cost is critical for an organization's financial success.

Building on this conceptual base, the research develops a starting point for managerial decisions associated with human capital using two parallel decision models. First, the Quality Function Deployment (QFD) technique is applied to map service industry business objectives with employee skill sets. This determines which job classifications are most critical. A weighting factor is then developed to identify skill importance. Concurrently, a linear programming model determines the impact of hiring and termination on costs. This approach provides a quantitative methodology that supports service industry managers in understanding both the strategic and tactical (bottom line) financial value of their Human Capital decisions. Armed with that knowledge, they can begin an employment decision process based on the quantitative information provided by these models and that integrates with other subjective and system based factors that must also be a part of a comprehensive human resources plan.

description: The modeling of income data has originated a century ago with the work of Vilfredo Pareto. Since then several authors have added immense literature about income distributions and income inequality measures. In the present paper, we have pointed out some recent works in income distributions and income inequality measures. Recently the potential of the quantile function has been discussed in parallel with the distribution function for modeling reliability and income data. So we have also included some quantile functions existing in the literature and their potentiality to model income data in the review. We derived the Lorenz curve, Gini index, Pietra index, Bonferroni index, Bonferroni curve, and Zenga curve for six distributions and checked the model adequacy of three distributions using real income data.

description: Background: Field-grown leafy vegetables can be damaged by biotic and abiotic factors, or mechanically damaged by farming practices. Available methods to evaluate leaf tissue damage mainly rely on colour differentiation between healthy and damaged tissues. Alternatively, sophisticated equipment such as microscopy and hyperspectral cameras can be employed. Depending on the causal factor, colour change in the wounded area is not always induced and, by the time symptoms become visible, a plant can already be severely affected. To accurately detect and quantify damage on leaf scale, including microlesions, reliable differentiation between healthy and damaged tissue is essential. We stained whole leaves with trypan blue dye, which traverses compromised cell membranes but is not absorbed in viable cells, followed by automated quantification of damage on leaf scale. Results: We present a robust, fast and sensitive method for leaf-scale visualisation, accurate automated extraction and measurement of damaged area on leaves of leafy vegetables. The image analysis pipeline we developed automatically identifies leaf area and individual stained (lesion) areas down to cell level. As proof of principle, we tested the methodology for damage detection and quantification on two field-grown leafy vegetable species, spinach and Swiss chard. Conclusions: Our novel lesion quantification method can be used for detection of large (macro) or single-cell (micro) lesions on leaf scale, enabling quantification of lesions at any stage and without requiring symptoms to be in the visible spectrum. Quantifying the wounded area on leaf scale is necessary for generating prediction models for economic losses and produce shelf-life. In addition, risk assessments are based on accurate prediction of the relationship between leaf damage and infection rates by opportunistic pathogens and our method helps determine the severity of leaf damage at fine resolution. © 2020 The Author(s).

description: In this paper, an improved GEF fast addition algorithm is proposed. The proposed algorithm reduces time and memory space. In this algorithm, carry is calculated on the basis of arrival timing of the operand's bits without overhead of sorting. Intermediate terms are generated from the most significant bit and the carry is generated from the least significant bit using the functions of efficient operators. This algorithm shows better performance for use in the fastest computational devices of the near future.

description: Background: Heavy atomic nuclei are often described using the Hartree-Fock-Bogoliubov (HFB) method. In principle, this approach takes into account Pauli effects and pairing correlations while other correlation effects are mimicked through the use of effective density-dependent interactions. Purpose: Investigate the influence of higher order correlation effects on nuclear binding energies using Skyrme's effective interaction. Methods: A cut-off in relative momenta is introduced in order to remove ultraviolet divergences caused by the zero-range character of the interaction. Corrections to binding energies are then calculated using the quasiparticle-random-phase approximation (QRPA) and second order many-body perturbation theory (MBPT2). Result: Contributions to the correlation energies are evaluated for several isotopic chains and an attempt is made to disentangle which parts give rise to fluctuations that may be difficult to incorporate on the HFB level. The dependence of the results on the cut-off is also investigated. Conclusions: The improved interaction allows explicit summations of perturbation series which is useful for the description of some nuclear observables. However, refits of the interaction parameters are needed to obtain more quantitative results.

description: ROADMAP is a multi-actor project, including multiple institutions and organisations as project partners from different countries. In each country, partners formed working groups so called “Living Labs” composed of stakeholders from different groups, such as vets, farmers, farmer institutions, pharmaceutical companies. There are 12 Living Labs (LL) in total and each LL works differently, focusing on four levels, 1) farming systems, 2) sector, 3) regulatory, and 4) societal – but no LL works on all four levels. To describe the outcomes of the living labs, technical leaflets have been developed for all living labs.

Rational choice and moral judgment as an insurmountable dichotomy for a theory of decisions

Subjects: Philosophical psychology (incl. moral psychology and philosophy of action)

description: From a philosophical point of view, in general we can clearly distinguish two cultures, that is, culture in the context of the natural sciences and culture in the context of the humanities. Attempts are now being made to propose a third notion of culture, one that involves rational choice and moral judgment in this discourse. Before the 2000s, people tended to separate rational choice from moral judgment. However, for some years now, Kant's concept of pure reason as the self-sufficiency of the subject has been questioned by intellectuals. There is a new definition of rationality, that is, rationality must be placed in a given situation to make sense, and it is context dependent, so it can be called situational rationality.

description: Yield development of agricultural crops over time is not merely the result of genetic and agronomic factors, but also the outcome of a complex interaction between climatic and site-specific soil conditions. However, the influence of past climatic changes on yield trends remains unclear, particularly under consideration of different soil conditions. In this study, we determine the effects of single agrometeorological factors on the evolution of German winter wheat yields between 1958 and 2015 from 298 published nitrogen (N)-fertilization experiments. For this purpose, we separate climatic from genetic and agronomic yield effects using linear mixed effect models and estimate the climatic influence based on a coefficient of determination for these models. We found earlier occurrence of wheat growth stages, and shortened development phases except for the phase of stem elongation. Agrometeorological factors are defined as climate covariates related to the growth of winter wheat. Our results indicate a general and strong effect of agroclimatic changes on yield development, in particular due to increasing mean temperatures and heat stress events during the grain-filling period. Except for heat stress days with more than 31°C, yields at sites with higher yield potential were less prone to adverse weather effects than at sites with lower yield potential. Our data furthermore reveal that a potential yield levelling, as found for many West-European countries, predominantly occurred at sites with relatively low yield potential and about one decade earlier (mid-1980s) compared to averaged yield data for the whole of Germany. Interestingly, effects related to high precipitation events were less relevant than temperature-related effects and became relevant particularly during the vegetative growth phase. Overall, this study emphasizes the sensitivity of yield productivity to past climatic conditions, under consideration of regional differences, and underlines the necessity of finding adaptation strategies for food production under ongoing and expected climate change. © 2020 The Authors.

description: Voice over Internet Protocol is a service from the Internet services that allows users to communicate with each other. Quality of Service is very sensitive to delay so that Voice over Internet Protocol needs it. The objective of this research is to study the effect of different queuing algorithms within the router on Voice over Internet Protocol Quality of Service. In this work, simulation tool OPNET Modeler is used to implement the proposed network (Voice over Internet Protocol Network). The proposed network is a private network for a company that has two locations located at two different countries around the world in order to simulate the communications within the same location as a local and the communications between two locations as a long distance and analyze Voice over Internet Protocol Quality of Service through measuring the major factors that affect the Quality of Service for Voice over Internet Protocol according to international telecommunication union standards such as: delay, jitter and packet loss. In this research, a comparison was carried out between different queue algorithms like First in First out (FIFO), Priority queue and Weight Fair Queuing and it was found that Priority queue and Weight Fair Queuing algorithms are the most appropriate to improve Voice over Internet Protocol Quality of Service .

description: Sexual signals indicate species identity and mate quality, and their importance for mate attraction is largely recognized. Recently, research in animal communication has started to integrate multiple signal modalities and evaluate their interactions. However, mate choice experiments across animal taxa have been limited to laboratory conditions, and assessments of multiple sexual signals under field conditions are still lacking. We take advantage of the divergence in visual and acoustic signals among populations of the Neotropical poison frog Oophaga pumilio to evaluate the importance of male advertisement calls and color patterns in female mate selection. Previous mate choice experiments in this species suggested color-assortative female mate preferences across many populations. Nevertheless, acoustic signals are crucial for sexual selection in frogs, and males of O. pumilio use advertisement calls to attract females. We hypothesize that both advertisement calls and coloration affect female mate selection in O.pumilio. To test this hypothesis we tested 452 receptive females from six populations in Costa Rica and Panama in their natural home ranges for preferences regarding local vs. non-local advertisement calls and color patterns. Overall, the calls overrode the effect of coloration, whereby most females preferred local over non-local calls. We found a tendency to prefer brighter (but not necessarily local) males in two populations. Furthermore, the strength of preferences varied geographically, and thus might be involved in prezygotic isolation among populations. The stronger effect of calls on mate attraction is associated with acoustic divergence between genetic groups in the species, while color pattern diversity is mostly located within one genetic group, i.e., not linked to large-scale population structure. Finally our data highlights the importance to consider an array of signal modalities in multiple wild populations in studies of behavioral isolation.

description: In order to get a broader view of the s-process nucleosynthesis we study the abundance distribution of heavy elements of 35 barium stars and 24 CEMP-stars, including nine CEMP-s stars and 15 CEMP-r/s stars. The similar distribution of [Pb/hs] between CEMP-s and CEMP-r/s stars indicate that the s-process material of both CEMP-s and CEMP-r/s stars should have a uniform origin, i.e. mass transfer from their predominant AGB companions. For the CEMP-r/s stars, we found that the r-process should provide similar proportional contributes to the second s-peak and the third s-peak elements, and also be responsible for the higher overabundance of heavy elements than those in CEMP-s stars. Which hints that the r-process origin of CEMP-r/s stars should be closely linked to the main r-process. The fact that some small $r$ values exist for both barium and CEMP-s stars, implies that the single exposure event of the s-process nucleosynthesis should be general in a wide metallicity range of our Galaxy. Based on the relation between $C_{r}$ and $C_{s}$, we suggest that the origin of r-elements for CEMP-r/s stars have more sources. A common scenario is that the formation of the binary system was triggered by only one or a few supernova. In addition, accretion-induced collapse(AIC) or SN 1.5 should be the supplementary scenario, especially for these whose pre-AGB companion with higher mass and smaller orbit radius, which support the higher values of both $C_{r}$ and $C_{s}$.

description: Objective: In the present paper we consider a two-state retrial queueing system with feedback having two heterogeneous parallel servers and impatient customers. Transient state probabilities for exact number of arrivals and departures from the system will be obtained when both, one or none of the servers is busy. Numerical and graphical solutions will also be obtained. Methods: The difference-differential equations governing the system are solved recursively, Laplace transform is then used to obtain the transient state probabilities for exact number of arrivals and departures from the system. Findings: Time dependent probabilities are obtained when both, one and none of the servers is busy. Numerical and Graphical solutions are also obtained using MATLAB programming. Novelty: In past research, models considered arrivals and departures from the orbit whereas in present model arrivals and departures from the system are studied along with the concept of feedback. Applications: This type of model is implemented in computer systems.

description: In the core accretion model for the formation of gas giant planets, runaway gas accretion onto a core is the primary requisite, triggered when the core mass reaches a critical value. The recently revealed wide diversity of the extrasolar giant planets suggests the necessity to further the understanding of the conditions resulting in the critical core mass that initiates runaway accretion. We study the internal structure of protoplanets under hydrostatic and thermal equilibria represented in terms of a polytropic equation of state to investigate what factors determine and affect the critical core mass. We find that the protoplanets, embedded in protoplanetary disks, have the same configuration as red giants, characterized by the envelope of the centrally-condensed type solution. Applying the theory of stellar structure with homology invariants, we demonstrate that there are three types of criteria for the critical core mass depending on the stiffness of polytrope and the nature of outer boundary condition. For the stiff polytropes of index $N \le 3$ with the Bondi radius as the outer boundary, the criterion governing the critical core mass occurs at the surface. For stiff polytropes with the Hill outer boundary and for soft polytropes of $N>3$, this criterion acts at the bottom of gaseous envelope. Further, we elucidate the roles and effects of coexistent radiative and convective zones in the envelope of critical core mass. Based on the results, we discuss the relevance of Bondi and Hill surface conditions and explore the parameter dependences of critical core mass.
