Hi

I am trying to making a scientifique poster in Context. I need some 
suggestions,
foreground an example, to start. Somebody has a nice example to share?
What is the correct scales for the fonts?

Have a nice day/night

Thanks to all

Jorge

This is an early version of a poster I have used. It is quite
non-standard but shows some options for placing things and fonts.

\startbuffer[Intro]
\BoxTitle{Introduction}

Experiments investigating the difference between finding something
vaguely famililar and actually recollected may be performed using the
``remember/know'' paradigm.  Subjects are required to specify whether
correctly recognized items were explicitly ``remembered'' or merely
familiar, ``known''.  In spite of experimental design difficulties, a
number of imaging studies have also been performed (Eldridge, Henson).
One difficulty in designing these imaging experiments is that one
would ideally like the subject to answer to questions at once in the
recognition situation: first, whether they recognize the item and if
they do, second, whether they ``remembered'' it or ``knew'' it.  In
the imaging context this is problematic and has been the generator of
some creativity in experimental design.  Instead of having the
subjects making two responses to the same stimulus in the same session
(like Eldridge et al) or having them choose between ``remember'',
``know'' or ``neither'' in the recognition situation (like Henson et
al), we collected the hits and fed them back to the subjects in a new
imaging session asking the subjects to state whether the previous
recognition event was one of recollecting or finding familiar, or that
they cannot recall. \par \stopbuffer

\startbuffer[Methods]
\BoxTitle{Methods}

************************Paradigm illustrated**********************
Twenty young and healthy volunteers were scanned while recognizing 80
words (encoded during an anatomical scan) out of 160. One subject was
discarded because of bizarre task-related movement. Three others were
discarded because they had less than five ``know'' events. The words
were presented for two seconds and the gap between them was four
seconds.  There were three sessions of 88 scans with a TR of 4.2
seconds.  After these three sessions, the subjects' hits were
extracted and two debriefing sessions were constructed containing the
hits, randomly ordered, with 30 percent null events.  We sorted hit
events in the recognition sessions according to whether they were
subsequently ``remembered'', ``known'' or ``guessed''.\par \stopbuffer

\startbuffer[DataAnal]
\BoxTitle{Data Analysis}

\kap{EPI} images were realigned, normalized and smoothed to 12mm
\kap{FWHM}. No slice timing correction was performed. For each person,
$t$-contrasts of the \kap{HRF}, as well as its temporal and dispersion
derivatives were estimated. These were used in a second-level
\kap{ANOVA} to estimate the difference between remember and know. \par
\stopbuffer

\startbuffer[Results]
\BoxTitle{Results}

Subjects performed very well on the task.  Hits minus false alarms
averaged 0.53.  65 percent of hits were 'remembered', 26 percent were
'known' and nine percent were 'guessed'.  The contrast between
'remembered' and 'known' hits at recognition shows in the
lingual/fusiform gyrus on the right and the precuneus on the left.
The contrast between 'remembered' and 'known' hits at debriefing
sessions shows activations also in the precuneus bilaterally and the
middle frontal gyrus on the right.

take a look at m-streams.tex

when you use streams, you can build your poster from snippets that are actually pages, i'e. you can then do most of the tricks that you normally do in the mvl (page stream)

The following example works fine on my computer (using ConTeXt ver:

\usemodule[streams]
\starttext
  \definestreamlayer[whatever][width=12cm]

  \startstreamlayer[whatever]
    \startitemize[columns,two][after=]
      \item one
      \item two
      \item three
      \item four
    \stopitemize
  \stopstreamlayer

  \framed[strut=no,align=normal]{\placestreamlayer[whatever]\obeydepth}

  \starttextstreamlayer[whatever]
    \startitemize[columns,two]
      \item one
      \item two
      \item three
      \item four

This is a great example. Many thanks. Another question: why only two 
columns?

Thanks a lot

Hi,

I always start tasks like that by setting the paper size and switching
\showframe ;). About the font size: the poster should be readable from 1.5
meter distance. It's good to start from at least 24 pt. You surely realise
that you have to be extremely concise in your texts, so you may end up at
something like 21 pt (which is suboptimal but acceptable).

Attached you find an example (figures not included). Feel free to modify
it, share and enjoy.

> Jorge

BTW, we'd appreciate if you used your real name in the From: header.

Have a nice towel day,
D.A.

\chapter{Introduction}

Personal Computer (PC) as a router is
\startitemize
\item Reliable and highly functional
\item Comparable to middle-class routers (e.g., CISCO~7500)
\stopitemize
But\dots
\startitemize
\item Configurable with difficulties (via \type{/etc} files)
\item Limited mainly by PCI system bus (up to 2~Gbps with 64bit/66MHz bus)
\stopitemize

The goal of the \externalfigure[liberouter][height=0.5\baselineskip]{}
project: IPv6 router solving
those limitations. How?
\startitemize
\item Hardware accelerator {\em Combo6}
\item XML based configuration system {\em Netopeer}
\stopitemize

\chapter{Router Architecture}

Combo6 is a PCI card containing FPGA, memories (SSRAMs and DRAM), expansion
connectors, and supporting logic. Network interfaces are mounted on an
expansion daughter card for interfaces to be changed easily.

\startlinecorrection
\midaligned{\externalfigure[combo6][height=12\baselineskip]}
\stoplinecorrection

Design rules (just pure instance of {\em hardware/software codesign}
principles):
\startitemize
\item Packet switching and filtering will be performed by Combo6
\item PC can do the rest; routing path calculations, configuration,
statistics computation
\item Communication through PCI is limited to configuration, routing table
updates, statistics collection, and exception handling
\item Usual Operating System tools can be used, like \type{ifconfig} and
routing daemons
\stopitemize

\chapter{Packet Processing in Hardware}

Key idea: Packet processing in FPGA is done by a chain of dedicated
processors with simple, specialized instruction sets designed for their
particular purposes. We call them {\em nanoprocessors}---they are
interpreted by FPGA's microcode. Instruction sets are \quotation{between
FSMs and RISC processors.}

\startitemize
\item Changing nanoprograms in runtime is possible (with no need of VHDL
compilation)---this differs from Partial Reconfiguration
\item VHDL tools are not needed to change nanoprograms, our free
development environment can be employed
\item New features can be added step-by-step
\item On the contrary, Partial Reconfiguration may produce more efficient
designs
\stopitemize

Packet processing is pipelined. A packet flows through the FPGA and
memories. An incoming packet is received by the Input Packet Buffer and
passed to the Header Field Extractor. The HFE pushes the body of the packet
into the dynamic memory. Meanwhile, it parses its headers and creates a
{\em Unified-header} and a structure reflecting actual arrangement of the
headers. The Unified-header is a fixed structure containing information
relevant for routing and filtering decisions.

The Lookup Processor (LUP) processes the Unified-header performing a lookup
nanoprogram. The lookup nanoprogram is kept in CAM and SRAM. Using CAM is
fast, unfortunately, IPv6 requires nearly 600~bits to check. Widest
available CAMs have less than 300~bits, therefore a combination of CAM
search and lookup instructions (conditional jumps) is used.

\startlinecorrection
\midaligned{\externalfigure[combo.1][height=8\baselineskip]}
\stoplinecorrection

Packet Replicator and Block of Output Queues (RQU) replicates the packet ID
to queues computed by LUP. Output Packet Editor modifies headers of the
packet before it is sent out. Operating system is one of the output
interfaces. It allows to deliver packets to the host computer as well as
handling packets hardware is not able to process.

\chapter{Software Support}

Software drivers are developed for NetBSD (and FreeBSD) and ported to
Linux. Driver operations include FPGA chip configuration, accessing
memories in the card, and hardware/software interface operations.

Other part of router software {\em hides presence of Combo6 in the host
computer}. The card should perform the same routing and filtering
functionality as the host computer itself, only faster. Host computer uses
routing table, configuration of interfaces, and firewall setting, Combo6
has to run the LUP nanoprocessor just once to make a decision how to handle
a packet.

To be able to combine routing table and firewall setting into one lookup
operation, we developed a concept of {\em routing/firewalling
table}---firewall rules are applied on routing table rows a-priori.

\chapter{Netopeer Configuration System}

PC based routers are running under various operating systems with various
configuration files causing problems to network administrators. To
overcome this we are working on a unified configuration environment {\em
Netopeer}. The primary configuration is kept in an XML repository. User
interfaces implement Command Line Interface, web interface, and SNMP.
Configurations for several operating systems and commercial routers can be
generated from the XML, also allowing to convert among the representations.

Hi

I am trying to making a scientifique poster in Context. I need some 
suggestions,
foreground an example, to start. Somebody has a nice example to share?
What is the correct scales for the fonts?

Have a nice day/night

Thanks to all

Jorge
