Order p^6 chiral couplings from the scalar K Pi form factor
Employing results from a recent determination of the scalar KPi form factor
F_0^KPi within a coupled channel dispersion relation analysis \cite{JOP01}, in
this work we calculate the slope and curvature of F_0^KPi(t) at zero momentum
transfer. Knowledge of the slope and curvature of the scalar KPi form factor,
together with a recently calculated expression for F_0^KPi(t) in chiral
perturbation theory at order p^6, enable to estimate the O(p^6) chiral
constants C_12^r=(0.3 +- 5.4)10^-7 and (C_12^r+C_34^r)=(3.2 +- 1.5)10^-6. Our
findings also allow to estimate the contribution coming from the C_i to the
vector form factor F_+^KPi(0) which is crucial for a precise determination of
|V_us| from K_l3 decays. Our result F_+^KPi(0)|_C_i^r=-0.018 +- 0.009, though
inflicted with large uncertainties, is in perfect agreement with a previous
estimate by Leutwyler and Roos already made twenty years ago.Comment: 19 pages, discussion of scale dependence of the chiral couplings

The Kappa in J/Psi -> Kpplus-piminus-Kminus-piplus
BES II data for J/Psi->K*(890)Kpi reveal a strong kappa peak in the Kpi
S-wave near threshold. Both magnitude and phase are determined in slices of Kpi
mass by interferences with strong Ko(1430), K1(1270) and K1(1400) signals. The
phase variation with mass agrees within errors with LASS data for Kpi elastic
scattering. A combined fit is presented to both BES and LASS data. The fit uses
a Breit-Wigner amplitude with an s-dependent width containing an Adler zero.
The kappa pole is at 760+-20(stat)+-40(syst) - i(420+-45+-60syst) MeV. The
S-wave I=0 scattering length a_0 = 0.23+-0.04 (in units of m(pi)) is close to
the prediction 0.19+-0.02 of Chiral Perturbation Theory.Comment: 20 pages, 5 figure
Performance Measurementof Xyz Government Institution's Contracts Workers Using Personal Balanced Scorecard Method
Implementation of good governance of bureaucracy system of Surabaya City Government, one of
them with developed performance-based salary program ( e-performance ) dedicated specially to Civil Servant.
But in reality agencies in Surabaya do not have the full use of civil servants as their human resources, thus
involving contractors as supporters of government performance processes. The purpose of this study is to
determine key performance indicators(KPI) and strategic objectives in XYZ Institution, determine the
importance of each KPI criterion, to understand the performance of each contractor at XYZ Government
Agency and provide improvement recommendations from the current employee performance. The unit of
analysis of this research is carried out at the General Section in the Sub Division of Administration with the
administrative position as the administrative contractor. The design of this study used a survey with
questionnaire data collection techniques and questionnaires. The method used is personal balanced scorecard by
formulating strategic targets and KPI by stakeholders from XYZ Agency. Weighting method using Analytic
Network Process method(ANP). From the research results obtained: the formulation of KPI and Strategy Target
has been formed with the highest level of KPI weight is KPI Total Late (0.1532). Total performance of the best
contractor performance is Mr. C (6.253) while the smallest total performance achievement is obtained Mr. K ie
(3.346). Recommendations include: Provide rewards, provide coaching, conduct regular control and evaluation
systems, provide socialization and provide slogans in the corner of the room on performance improvement
Whitham modulation theory for the Kadomtsev-Petviashvili equation
The genus-1 KP-Whitham system is derived for both variants of the
Kadomtsev-Petviashvili (KP) equation (namely, the KPI and KPII equations). The
basic properties of the KP-Whitham system, including symmetries, exact
reductions, and its possible complete integrability, together with the
appropriate generalization of the one-dimensional Riemann problem for the
Korteweg-deVries equation are discussed. Finally, the KP-Whitham system is used
to study the linear stability properties of the genus-1 solutions of the KPI
and KPII equations; it is shown that all genus-1 solutions of KPI are linearly
unstable while all genus-1 solutions of KPII {are linearly stable within the
context of Whitham theory.Comment: Significantly revised versio
Multivariate KPI for energy management of cooling system in food industry
Within EU, the food industry is currently ranked among the energy-intensive sectors, mainly as a consequence of the cooling
system shareover the total energy demand.
As such, the definition of appropriate key performance indicators (KPI) for ammonia chillers can play a strategic role for the
efficient monitoring of the energy performance of the cooling systems.
The goal of this paper is to develop an appropriate management approach, to account for energy inefficiency of the single
compressors, and to identify the specific variables driving the performance outliers.
To this end, a new KPI is proposed which correlates the energy consumption and the different process variables. The construction
of the new indicator was carried out by means of multivariate statistical analysis, in particular using Kernel Partial Least Square
(KPLS).This method is able to evaluate the maximum correlation between dataset and energy consumption employing nonlinear
regression techniques.
The validity of the new KPI is discussed on a case study relevant to the cooling system of a frozen ready meals industry. The
assessment of the proposed metric is one against Specific Energy Consumption (SEC) like indicator, typically used in the context
of the Energy Management Systems
